Rebuilding American Alliances in a Changing Western World

 

A Strategy for Transatlantic Renewal, Strategic Diversification, and a Broader Five Eyes Partnership

Introduction: The Limits of Restoration

The next American president may inherit a foreign-policy challenge that cannot be resolved simply by changing the tone of American diplomacy. After years of political turbulence, disagreements over trade, disputes about defense commitments, and growing uncertainty about the reliability of American leadership, the relationships that once formed the foundation of the Western alliance may have undergone changes that cannot easily be reversed.

For much of the postwar era, American presidents could assume that the basic architecture of Western cooperation would endure regardless of temporary political disagreements. The United States and Western Europe shared a common strategic outlook, supported by NATO, deep economic integration, and a broad commitment to the institutions of the international order. Individual governments might disagree over particular policies, but the underlying alliance remained intact.

That assumption may no longer be sufficient. The political transformation of Europe, including the rise of the National Rally in France and Alternative for Germany (AfD), has introduced new uncertainties into the future of European integration and transatlantic cooperation. At the same time, the European Union has increasingly emphasized strategic autonomy, economic sovereignty, and the development of independent defense and technological capabilities. These developments reflect forces within European politics that extend beyond any single American administration.

The next American president may therefore discover that the Western alliance cannot simply be reconstructed in its previous form. Even if Washington seeks reconciliation, European leaders may conclude that maintaining greater political, economic, and strategic distance from the United States better serves their long-term interests.

If that occurs, the United States should respect Europe's decision rather than attempt to force a restoration of the old relationship. American foreign policy must recognize that alliances are voluntary arrangements among sovereign nations, not permanent obligations to preserve a particular geopolitical configuration.

But respecting Europe's decision does not mean accepting a diminished American role in the world. It means pursuing other opportunities for international cooperation. One such opportunity lies in the Five Eyes partnership among the United States, United Kingdom, Canada, Australia, and New Zealand. Originally developed as an intelligence-sharing arrangement, Five Eyes possesses the institutional foundations, historical relationships, and economic complementarities that could support a much broader partnership.

The United States should therefore pursue a strategy of transatlantic renewal first, strategic diversification if necessary. It should offer Europe a genuine opportunity to rebuild and modernize the Western alliance while preparing to deepen relationships elsewhere if European leaders decline that opportunity. The objective should not be to abandon Europe or replace one alliance with another. It should be to ensure that the future of American international cooperation does not depend entirely upon the willingness of any single group of countries to restore the relationships of the past.

I. The Western Alliance Cannot Be Rebuilt by Washington Alone

The Western alliance emerged from the extraordinary geopolitical circumstances following the Second World War. Western Europe had been devastated by war, its economies required reconstruction, and the Soviet Union represented a formidable military and ideological challenge. The United States possessed the economic strength, military capabilities, and political influence necessary to help rebuild Europe and organize its collective defense.

The resulting transatlantic relationship was never entirely symmetrical. American military power provided the ultimate security guarantee for Western Europe, while American economic assistance, investment, and market access helped support European recovery and prosperity. In return, the United States gained strategic allies, forward military positions, and a more stable international environment in which its economic and political influence could flourish. This arrangement served both sides, even if the distribution of responsibilities was unequal.

Over time, however, the circumstances that originally justified the relationship changed. The Soviet Union collapsed. European economies recovered and became wealthy, sophisticated industrial societies. The European Union developed into a major economic and regulatory power. Meanwhile, American strategic attention increasingly expanded beyond Europe toward Asia and the Indo-Pacific.

The relationship evolved, but many of its institutional assumptions remained rooted in the postwar period. Recent American political developments have added another complication: uncertainty about the continuity of American commitments. European governments must now consider not only the policies of the sitting American president but also the possibility that those policies could change dramatically following subsequent elections.

A future president may offer renewed commitments to European security, trade, and cooperation, but European leaders may question whether those commitments will survive another change of administration. Trust, once weakened, cannot necessarily be restored through diplomatic assurances alone.

The next American president could make a sincere and substantial effort to rebuild transatlantic relations and still encounter European governments that prefer greater independence from Washington. This possibility must be incorporated into American strategic planning. A durable alliance requires willing participants on both sides. The United States can offer cooperation, negotiate agreements, and demonstrate reliability, but it cannot compel European governments to embrace a closer relationship. Nor should it attempt to do so.

The sovereignty that underpins the Western democratic tradition necessarily includes the right of European nations to determine their own foreign-policy priorities. If those priorities lead toward greater strategic distance from Washington, the United States must be prepared to adapt.

II. Europe’s Changing Political Landscape

The challenge of rebuilding the Western alliance is complicated by political developments within Europe itself. The rise of nationalist, populist, and Euroskeptic movements has altered the political environment in several major European countries.

In France, the National Rally has challenged traditional assumptions about European integration, national sovereignty, immigration, and the distribution of authority between Paris and Brussels. In Germany, the AfD has challenged aspects of the country's established political consensus, including policies concerning European integration and international commitments.

These movements differ in their objectives, internal composition, and foreign-policy positions. They should not be treated as interchangeable, nor should their rise be assumed to produce any particular electoral outcome. Nevertheless, their growing political significance illustrates a broader reality: the European political landscape is becoming more contested.

A future American administration may find itself negotiating not with the familiar European political establishment of previous decades, but with governments representing substantially different domestic coalitions and strategic priorities.

At the same time, support for greater European autonomy extends well beyond nationalist or populist movements. Many European leaders who remain committed to NATO and transatlantic cooperation nevertheless believe that Europe should develop stronger independent military capabilities, greater technological sovereignty, and reduced dependence on external economic powers.

This position is not inherently hostile to the United States. Indeed, a Europe capable of assuming greater responsibility for its own defense could strengthen the transatlantic relationship by making it more reciprocal. But strategic autonomy can take different forms. One version envisions a stronger Europe cooperating with the United States as a more equal partner. Another envisions Europe deliberately reducing its dependence on Washington and developing a more independent position between major global powers.

These approaches could produce very different futures for the Western alliance. The next American administration should not assume that European strategic autonomy necessarily means transatlantic estrangement. It should seek to determine whether European leaders want greater independence within a renewed partnership or greater distance from the partnership itself. That distinction should guide American diplomacy.

III. Restoration Should Be the First Offer, Not the Only Strategy

The United States has compelling reasons to seek renewed cooperation with continental Europe. The European Union represents one of the world's largest economic markets. European countries possess advanced industrial capabilities, scientific institutions, substantial financial resources, and significant diplomatic influence.

France and Germany remain especially important partners, while the broader European community includes countries with essential military, technological, and geographic capabilities. The United States and Europe also share extensive commercial relationships, security interests, and institutional connections developed over generations. Allowing those relationships to deteriorate unnecessarily would impose costs on both sides.

Consequently, the next American president should begin by offering a serious effort to renew and modernize the transatlantic partnership. But this should not be an exercise in nostalgia. The objective should not be to reconstruct the exact relationship that existed during the Cold War or the decades immediately following it. The international environment has changed too substantially for that to be either realistic or desirable.

Instead, Washington should propose a new arrangement built around reciprocal responsibilities and shared interests. In security affairs, this could involve modernizing NATO's collective-defense commitments, strengthening European military capabilities, and reconsidering how alliance obligations apply to threats beyond the traditional North Atlantic theater.

In economic affairs, it could involve reducing trade barriers, improving regulatory cooperation, coordinating strategic investments, and developing common approaches to emerging technologies. In diplomacy, it could involve recognizing Europe's desire for a greater independent voice while preserving the ability to coordinate on matters of common concern.

The central principle should be reciprocity. The United States should no longer approach transatlantic relations primarily as a security guarantee that America extends to Europe. It should seek a relationship among capable partners that assume meaningful responsibilities for one another's security and prosperity.

Such an offer would give European governments a genuine opportunity to participate in constructing a modernized Western alliance. But the United States should also recognize that the offer may not be accepted. European leaders may decide that their political interests, economic priorities, or visions of European sovereignty are better served by maintaining greater distance from Washington.

If that is their conclusion, the United States should respect it. There would be little strategic value in attempting indefinitely to restore an alliance whose participants no longer share the same ambitions for its future. Respecting such a decision would not require abandoning NATO commitments, withdrawing from European security arrangements, or treating Europe as an adversary. Existing treaty obligations would remain in force unless changed through lawful procedures.

Rather, it would mean accepting that the scope for deeper integration had reached a limit and redirecting some diplomatic attention toward partners interested in pursuing more ambitious cooperation. The United States should offer Europe a renewed partnership, but it should not make the reconstruction of its international alliances dependent upon Europe's acceptance of that offer.

IV. Five Eyes: From Intelligence Cooperation to Strategic Partnership

If European leaders decline a deeper transatlantic partnership, the United States should examine opportunities to expand cooperation among countries with which it already possesses substantial institutional relationships. The Five Eyes partnership offers one such possibility.

Comprising the United States, United Kingdom, Canada, Australia, and New Zealand, Five Eyes originated in wartime and postwar intelligence cooperation. Over subsequent decades, it developed into one of the world's most enduring and closely integrated intelligence-sharing relationships.

Its importance lies not merely in the exchange of information but in the institutional trust required to sustain that exchange. Intelligence cooperation involves some of the most sensitive activities undertaken by governments. Countries participating in such arrangements must develop extensive procedures for protecting classified information, coordinating operations, and maintaining confidence in one another's institutions.

The existence of these relationships does not guarantee agreement on trade, immigration, industrial policy, or economic integration. Those matters involve different political interests and constituencies. Nevertheless, Five Eyes provides a foundation of familiarity and cooperation that would be difficult to reproduce quickly among countries without comparable histories.

The five countries also possess several characteristics that could facilitate a broader partnership. They share English as a common working language, broadly compatible legal traditions, established democratic institutions, and extensive commercial and cultural connections. Their geographic distribution provides a presence across North America, Europe, and the Indo-Pacific. Their economies possess complementary strengths in finance, technology, energy, agriculture, natural resources, research, and advanced manufacturing.

And critically, none belongs to the European Union. The United Kingdom's departure from the EU has created additional flexibility for negotiating independent economic arrangements, although its continued commercial dependence on European markets means that any new partnership would need to remain compatible with important existing relationships.

These characteristics create an opportunity to consider Five Eyes as more than an intelligence-sharing framework. It could become the foundation of a broader economic, technological, and strategic partnership among countries already accustomed to cooperating on matters of national importance.

V. The Economic Case for a Five Eyes Partnership

The economic potential of a broader Five Eyes arrangement deserves particular attention. The five countries collectively possess a large, wealthy consumer market, significant pools of investment capital, advanced research institutions, and substantial natural resources. Their economic strengths are also complementary rather than identical.

The United States possesses the largest economy within the group, deep capital markets, leading technology companies, and extensive industrial and scientific capabilities. Canada contributes substantial energy resources, critical minerals, agricultural production, advanced manufacturing, and geographic integration with the American economy.

Australia offers major mineral and energy resources, sophisticated research institutions, and an important economic and strategic position in the Indo-Pacific. The United Kingdom contributes financial services, advanced research, professional services, aerospace, pharmaceuticals, and internationally connected commercial institutions. New Zealand offers agricultural expertise, specialized technology industries, renewable-energy capabilities, and an established Pacific presence.

A deeper economic partnership could use these complementarities to increase investment, reduce barriers, and strengthen supply chains. One possibility would be a comprehensive Five Eyes economic agreement that progressively reduces tariffs and unnecessary regulatory barriers among participating countries. Another would be the creation of common frameworks for recognizing professional qualifications, facilitating investment, and encouraging scientific and technological collaboration.

The partnership could also coordinate strategic industrial development. For example, critical minerals extracted in Australia or Canada could be processed and incorporated into advanced manufacturing supply chains across participating countries. Research institutions in Britain, Canada, Australia, New Zealand, and the United States could collaborate on artificial intelligence, quantum computing, biotechnology, and next-generation energy systems.

Rather than requiring each country to develop every strategic capability independently, the members could coordinate investment and specialization. Such an approach could increase economic resilience without abandoning the advantages of international trade.

However, an economic partnership should not be confused with a fully integrated economic union. A customs union, common external tariff, or unrestricted labor market would involve far greater political commitments and could conflict with existing agreements. The more practical initial objective would be a flexible economic community that reduces barriers where mutually beneficial while preserving national control over sensitive policies.

Nor should the potential economic gains be exaggerated. Existing trade agreements already provide substantial market access among several Five Eyes members, and the United States and Canada are deeply integrated through the United States-Mexico-Canada Agreement. The United Kingdom, Australia, and New Zealand also participate in the Comprehensive and Progressive Agreement for Trans-Pacific Partnership.

A new framework would therefore need to offer benefits beyond simply duplicating arrangements that already exist. Its distinctive contribution could lie in combining trade liberalization with investment coordination, technological cooperation, industrial resilience, and strategic economic security. That combination would make it more ambitious than an ordinary free-trade agreement.

VI. The United Kingdom as a Potential Bridge

The United Kingdom would occupy a particularly important position in any effort to expand Five Eyes. Britain is simultaneously a major European economy, a NATO member, a permanent member of the United Nations Security Council, a leading financial center, and one of America's closest intelligence and defense partners.

Its departure from the European Union also gives it a distinct institutional position. Unlike France or Germany, Britain can negotiate its own trade agreements independently of the EU's common commercial policy. This creates opportunities for the United States and United Kingdom to pursue deeper bilateral economic cooperation that could eventually serve as a model for broader Five Eyes integration.

A future American administration could begin by negotiating expanded arrangements concerning financial services, technology, investment, professional mobility, and strategic manufacturing. Successful agreements could then provide a foundation for discussions with Canada, Australia, and New Zealand.

Britain could also serve as a diplomatic bridge between an emerging Five Eyes economic partnership and continental Europe. This role would be especially important if European leaders preferred a more independent relationship with Washington.

A stronger Five Eyes partnership need not require Britain to weaken its European commercial relationships. Indeed, the arrangement would be more attractive if it expanded Britain's international economic opportunities rather than forcing a choice between competing blocs. The objective should be to create additional channels of cooperation, not to construct artificial barriers between countries that continue to share substantial interests.

VII. The Problem of American Reliability

Any proposal to expand Five Eyes must confront an obvious difficulty. If European governments have become concerned about the reliability of American commitments, why would Canada, Australia, New Zealand, or Britain necessarily feel differently?

These countries have their own political systems, economic interests, and strategic priorities. Their longstanding relationships with Washington do not make them immune to concerns about abrupt changes in American policy. Indeed, some may be especially sensitive to such changes because of their substantial economic dependence on the United States.

The next American administration therefore could not assume that its Five Eyes partners would automatically embrace deeper economic integration. It would need to demonstrate that the proposed partnership offered genuine reciprocal benefits and would not become an instrument for unilateral American demands.

This is where institutional design becomes essential. The United States should seek agreements that are durable across administrations, supported by domestic political constituencies, and grounded in clearly defined mutual obligations. Where appropriate, major trade commitments should receive congressional approval rather than relying exclusively on executive arrangements that future presidents could reverse.

A broader partnership could establish regular meetings among heads of government, permanent economic and technological working groups, transparent dispute-resolution mechanisms, and agreed procedures for reviewing commitments.

These institutions would not eliminate political disagreements. No treaty can guarantee that governments will maintain identical policies indefinitely. But they could raise the political and economic costs of arbitrary reversals and make cooperation more predictable.

The larger lesson is that American credibility cannot be restored merely by choosing different partners. It must be rebuilt through the way the United States conducts its relationships. A successful Five Eyes economic partnership would therefore require a change in American diplomatic practice as much as a change in institutional structure.

VIII. Avoiding the Creation of Rival Western Blocs

An expanded Five Eyes partnership could create opportunities, but it could also introduce new risks. The most serious would be the possibility that continental European governments interpret it as an attempt to establish an Anglo-American economic bloc in opposition to the European Union.

Such a development could deepen the very divisions the next American president initially sought to repair. It could also create unnecessary complications for countries such as Britain and Canada, whose prosperity depends upon maintaining diverse international commercial relationships.

The United States should therefore distinguish between diversification and exclusion. Diversification means developing additional partnerships so that American foreign policy is not dependent upon any single institutional relationship. Exclusion means constructing new partnerships specifically to isolate countries that have declined closer cooperation.

The former can strengthen American diplomatic flexibility. The latter could unnecessarily fragment the international order. An expanded Five Eyes economic partnership should consequently remain compatible with continued trade, investment, and diplomatic cooperation with Europe.

The United States should make clear that European governments remain welcome partners in areas of shared interest, even if they choose not to pursue deeper institutional integration with Washington. The same principle should apply beyond Europe.

Japan, South Korea, and other important American partners possess technological, industrial, and strategic capabilities that would be valuable in many cooperative initiatives. They need not become members of Five Eyes to participate in joint research, supply-chain development, investment arrangements, or selected economic-security projects.

This suggests that the ultimate objective should not be the creation of a closed Five Eyes bloc. It should be the development of a more flexible international architecture in which different partnerships perform different functions and cooperate where their interests overlap.

IX. Toward a Networked System of American Alliances

For much of the twentieth century, American foreign policy organized international relationships around relatively distinct geographic and institutional arrangements. NATO formed the foundation of collective defense in Europe and the North Atlantic. Bilateral treaties and regional arrangements supported American security commitments in Asia. International economic institutions facilitated trade, finance, and investment.

These arrangements were products of their historical circumstances. The twenty-first century presents a different set of challenges. Economic production is organized through global supply chains. Technological development increasingly influences national security. Cyber threats cross borders almost instantaneously. Strategic competition extends across military, financial, industrial, scientific, and informational domains.

Under these conditions, American alliances may benefit from becoming more flexible and interconnected. NATO could remain the principal collective-defense framework for the North Atlantic. The European Union could remain a major economic and diplomatic partner, even if it chooses greater strategic autonomy. Five Eyes could develop into a deeper economic, technological, and intelligence partnership.

American relationships with Japan, South Korea, and other Indo-Pacific countries could support regional security and advanced industrial cooperation. Additional arrangements could connect these partnerships through common technological standards, research initiatives, investment frameworks, and supply-chain agreements.

Such a system would not require every country to participate in every institution or accept every American strategic objective. Instead, it would recognize that international cooperation can operate at different levels among countries with overlapping but not identical interests.

This would also provide resilience against political change. If one relationship became less cooperative, other partnerships could continue functioning. If political conditions later improved, countries could expand cooperation without requiring a comprehensive reconstruction of the entire international system.

The United States would remain deeply engaged internationally, but its relationships would no longer depend upon preserving one particular conception of the Western alliance.

X. A Practical Strategy for the Next American Administration

A future American president pursuing this approach should proceed deliberately. The first priority should be diplomatic engagement with Europe. Washington should convene consultations with major European governments and EU institutions to determine whether there is sufficient political willingness to negotiate a modernized transatlantic partnership.

The American proposal should address defense reciprocity, trade and investment, technological cooperation, and the institutional durability of future commitments. European governments should be given a genuine opportunity to shape the arrangement rather than merely accept an American blueprint.

The second priority should be assessing the response. A European preference for greater military self-sufficiency should not automatically be interpreted as a rejection of closer relations. Indeed, stronger European defense capabilities could complement American interests. The relevant question would be whether European governments are willing to pursue substantive reciprocal agreements that strengthen the broader partnership.

If they are, the United States should proceed with transatlantic renewal. If they are not, Washington should acknowledge the limits of the relationship without treating the outcome as a diplomatic defeat.

The third priority, if deeper transatlantic renewal proves unattainable, should be an exploration of expanded Five Eyes cooperation. The American president could convene a summit of the five governments to discuss the feasibility of a broader economic and strategic framework.

Initial negotiations could focus on areas where mutual benefits are comparatively clear: critical minerals, technological research, defense-industrial cooperation, professional qualifications, and investment barriers. More ambitious trade and mobility agreements could follow if the initial arrangements demonstrate sufficient value.

Importantly, the Five Eyes partners should have an equal opportunity to determine the direction of the initiative. The United States would bring the largest economy and greatest military resources to the table, but the partnership's legitimacy would depend upon treating its members as sovereign participants rather than subordinate components of an American strategy.

Finally, the administration should preserve channels for renewed European cooperation. Political circumstances change. European governments that initially prefer greater distance from Washington may later reconsider. American domestic politics may also evolve.

A sound foreign policy should leave room for such developments. The objective is not to replace one rigid alliance structure with another. It is to construct an adaptable network of relationships capable of responding to changing international circumstances.

Conclusion: Building the Future Rather Than Reconstructing the Past

The next American president may face a world in which the traditional Western alliance remains important but no longer possesses the political cohesion that characterized much of the postwar period.

The United States should not welcome unnecessary divisions with Europe. The economic, diplomatic, and security relationships developed across the Atlantic remain too valuable to discard casually. A serious effort to restore and modernize those relationships should therefore be among the first foreign-policy priorities of the next administration.

But the United States must also recognize the limits of its influence. The Western alliance cannot be rebuilt through American determination alone. It requires European governments that share the ambition of constructing a renewed partnership.

If continental European leaders conclude that greater distance from Washington better serves their national and collective interests, the United States should respect that decision. It should neither attempt to coerce Europe into closer alignment nor allow the absence of European enthusiasm to prevent the development of other international relationships.

Instead, Washington should pursue new opportunities for cooperation among willing partners. An expanded Five Eyes partnership offers one possible avenue. By building upon longstanding intelligence cooperation and extending it into trade, investment, technology, strategic industries, and economic security, the United States, United Kingdom, Canada, Australia, and New Zealand could explore a more ambitious institutional relationship.

Such a partnership would not replace NATO, eliminate the importance of Europe, or resolve every uncertainty surrounding American foreign policy. Nor would its success be automatic. It would require careful negotiation, credible American commitments, and genuine agreement among the participating countries.

But it would demonstrate that the United States possesses options beyond attempting indefinitely to reconstruct the international arrangements of an earlier era. The broader lesson extends beyond Five Eyes. American foreign policy should not become so attached to the institutions of the past that it loses the ability to construct institutions for the future.

After the Second World War, American leaders recognized that the international system had fundamentally changed. Rather than attempting simply to restore the prewar order, they helped create new arrangements suited to the geopolitical realities of their time. The next generation of American leaders may confront a different but related challenge.

The task will be to preserve the benefits of existing alliances wherever possible while developing new forms of cooperation wherever necessary. The United States should seek a renewed Western alliance, but it should not assume that the Western alliance must forever take the form it acquired during the twentieth century.

America should extend its hand to Europe, but it should not stand still if Europe declines to take it. The future of American leadership will depend not merely upon the ability to repair old relationships, but upon the willingness to build new ones.
