Alliance, Attrition, and Abandonment: The Strategic Logic Behind America's Growing Isolation in Global Conflict: Global Warfare

Executive Summary

Who Wins Wars and Who Loses Them: An Analysis of Military Victory, Strategic Defeat, and the Geopolitics of Power in the Twenty-First Century

The question of who wins wars — and why — is among the most consequential in all of international relations.

It is a question that has animated strategists, politicians, historians, and philosophers for millennia, and yet it remains imperfectly understood even in the contemporary era.

The dominant assumption is that material power decides conflicts: the nation with the larger army, more advanced weapons, and a deeper treasury will prevail.

History, however, repeatedly subverts this assumption.

From the American defeat in Vietnam to the Soviet collapse in Afghanistan, from the French capitulation in Algeria to the ongoing impasse created by Iran's strategic resistance against an American-Israeli air campaign initiated on February 28th, 2026, the evidence is overwhelming that victory in war is a far more complex achievement than mere material superiority can guarantee.

This article argues that war's outcome is shaped by a constellation of interlocking variables: economic endurance, societal cohesion, quality of political leadership, legitimacy in the eyes of domestic and international audiences, alliance management, and the capacity to adapt strategically over time.

The nation that manages these variables most effectively — not simply the one that fields the most powerful military force — tends to emerge victorious.

Conversely, nations that lose wars do so not merely because they are outgunned but because they are outgoverned, outlasted, or out-legitimized.

In the context of 2026, these dynamics are playing out with striking historical resonance.

The United States, nominally the world's most powerful military state, is conducting a major strike campaign against Iran while simultaneously confronting a fraying NATO alliance, European allies openly refusing to support its military operations, and a domestic political environment profoundly divided over the wisdom and legality of the conflict.

Understanding why wars are won and lost requires situating these contemporary tensions within the deep structure of strategic history.

Introduction: The Paradox of Power and Outcome

From Battlefields to Boardrooms: The Hidden Forces That Decide Which Nations Prevail in War

War is the ultimate test of national power, yet its results are frequently paradoxical.

The stronger power does not always prevail; the weaker party does not always yield.

This paradox, well recognized in strategic studies, has been discussed extensively by scholars ranging from Carl von Clausewitz to Martin van Creveld, and more recently by analysts like Phillips Payson O'Brien, whose work War and Power examines the structural determinants of victory and defeat from the nineteenth century to the present day.

O'Brien's central argument — drawn from systematic analysis of modern warfare — is that winning a war depends less on tactical brilliance in any single engagement than on three interlocking capacities: the ability to conduct complex operations across multiple domains, the capacity to regenerate military power through economic and industrial mobilization, and the effectiveness with which a state cooperates with and maintains its alliances.

These three pillars — operational complexity, regeneration, and alliance cohesion — frame the analytical structure of this article and allow us to evaluate not only the historical record of wartime victory and defeat but also the unfolding strategic reality of the current moment.

The landscape of contemporary conflict is defined by new variables that O'Brien's framework must accommodate: the role of information warfare and narrative control, the growing importance of economic sanctions as instruments of coercion, the fragility of domestic political consensus in democracies, and the erosion of multilateral institutional authority.

When these variables are integrated into the analysis, the picture that emerges is both illuminating and alarming.

Historical Foundations: What Wins Wars

The Anatomy of Victory and Defeat: Why Alliances, Economies, and Resolve Determine War's Outcome

The history of warfare from the late nineteenth century to the present provides a rich empirical foundation for understanding the determinants of military victory. Several defining patterns recur across the historical record with sufficient regularity to constitute structural laws of strategic behavior.

The first is the primacy of economic and industrial capacity.

The outcome of the two World Wars was settled not primarily on the battlefield but in the factory, the shipyard, and the laboratory.

The Allied victory in the First World War was made possible by the superior industrial output of Britain, France, and the United States, which eventually overwhelmed German productive capacity.

In the Second World War, the decisive factor was the ability of the Allied coalition — particularly the United States and Soviet Union — to regenerate military forces at a rate the Axis powers could not match.

Germany and Japan were both highly capable tactical and operational militaries.

What they lacked was the economic depth and alliance structure to sustain multi-front campaigns against adversaries whose productive capacity continuously expanded while their own contracted.

The second structural determinant is alliance cohesion.

No major war in the modern era has been won by a single power operating entirely alone.

The ability to forge, sustain, and effectively coordinate with allies has been a decisive variable in every major conflict since the Napoleonic Wars.

Britain's ability to mobilize coalition partners, the United States' construction of the wartime Grand Alliance with the Soviet Union and Commonwealth nations, and NATO's collective deterrence during the Cold War all illustrate the strategic premium on alliance management.

Conversely, Germany's failure to align its strategic aims effectively with Japan and Italy in the Second World War, and the United States' failure to sustain South Vietnamese political legitimacy or build durable Afghan state institutions, illustrate how even militarily powerful states fail when alliance and partnership structures collapse.

The third determinant is political legitimacy and domestic cohesion.

Wars are not won solely on foreign battlefields; they are also sustained or surrendered in domestic political arenas.

The American experience in Vietnam is paradigmatic: the United States possessed decisive military advantages and inflicted enormous casualties upon North Vietnamese and Viet Cong forces, yet it lost the war because it could not sustain domestic political consensus, could not convince the South Vietnamese government to develop legitimate administrative authority, and could not prevail in the narrative contest over the war's justice and purpose.

The same dynamic played out in the Soviet Union's Afghanistan campaign from 1979 to 1989, and again in the United States' post-2001 Afghan engagement, which ended in the total collapse of the Kabul government in August 2021 after 20 years of investment exceeding $2 trillion.

Why Nations Lose Wars: The Structural Pathology of Defeat

If the structural determinants of victory are economic depth, alliance cohesion, and domestic legitimacy, then the pathologies of defeat are their inversions.

Nations lose wars when they overestimate their own material power, underestimate the resilience and adaptability of their adversaries, fail to maintain alliance solidarity, and exhaust domestic political will.

The phenomenon of powerful states losing wars to weaker opponents has become one of the defining strategic puzzles of the post-1945 era.

Political scientist Andrew Mack's influential concept of "asymmetric conflict" offers a partial explanation: in wars where one side has dramatically more to lose than the other, the weaker side frequently prevails because its intensity of motivation compensates for its material inferiority.

The Viet Minh's defeat of France at Dien Bien Phu in 1954, the Hezbollah campaign that forced Israeli withdrawal from southern Lebanon in 2000, and the Taliban's 20-year resistance to American power all illustrate this principle.

But motivation asymmetry alone does not fully explain why great powers lose wars.

A more complete diagnosis must incorporate what might be called "strategic narcissism" — the tendency of powerful states to project their own assumptions, values, and strategic logic onto their adversaries. ries, and to plan wars based on what they expect the enemy to do rather than what the enemy is actually doinglly capable of doing.

The United States invaded Iraq in 2003 with a planning assumption that the conflict would last weeks, that Iraqis would welcome liberation, and that a functional state would emerge rapidly.

Instead, the United States found itself in a decade-long counterinsurgency that cost over 4,400 American lives and an estimated $2 trillion, with the strategic beneficiary of the destabilization being Iran — the very state the campaign was partly designed to contain.

Economic attrition also explains much of why wars are lost. Extended conflicts impose cumulative costs that disproportionately damage the side with less institutional resilience.

The war in Ukraine has demonstrated this principle with stark clarity: Russia's invasion, initially expected to achieve rapid regime change in Kyiv within days, has instead produced a war of attrition that has drained Russian economic reserves, accelerated Western European rearmament, and exposed critical limitations in Russian military logistics and command structure.

A 4th dimension of military defeat is what might be termed "legitimacy erosion." Wars that cannot be justified to domestic and international audiences gradually lose the political capital necessary to sustain them.

As legitimacy erodes, alliance partners withdraw, domestic constituencies defect, and the financial and human costs of continued fighting become politically unsustainable.

This is the precise dynamic now observable in the American-led campaign against Iran, where European NATO allies have explicitly refused to contribute military assets, domestic American opinion on the conflict remains divided, and the international community has not conferred the multilateral authorization that would grant the operation legitimacy under international law.

The Iran Conflict: A Strategic Case Study in Real Time

Fire Over Tehran, Cracks in Brussels: How Trump's Wars Are Redrawing the Geopolitical Landscape

The ongoing American-Israeli military campaign against Iran, initiated on February 28, 2026, constitutes the most significant test of the principles governing victory and defeat since the 2003 invasion of Iraq.

The campaign's stated objectives — preventing Iranian nuclear weapons acquisition, dismantling Iran's ballistic missile program, neutralizing Iranian naval forces in the Persian Gulf, and destroying the operational capacity of Iran's Axis of Resistance proxy network — are expansive, strategically ambitious, and only partially achievable through air power alone.

The campaign began with precision strikes by American and Israeli forces targeting Iranian military, security, and nuclear infrastructure.

The Natanz nuclear facility in Isfahan Province, Iran's primary uranium enrichment site, was struck on March 2nd, 2026, sustaining severe damage to at least three major structures as confirmed by satellite imagery.

Additional strikes followed on March 21, 2026, with Iran confirming a joint American-Israeli attack on Natanz while reporting no radioactive leakage from the damaged facility.

From a military operational standpoint, the early phases of the campaign demonstrated considerable effectiveness.

The United States and Israel leveraged their combined air superiority, electronic warfare capabilities, and precision munitions to degrade Iranian air defense networks, suppress surface-to-air missile systems, and strike hardened underground facilities.

Israel's experience with Iran's air defense architecture from the June 2025 conflict provided critical intelligence and targeting data that enhanced the effectiveness of the February 28th operation.

However, applying O'Brien's analytical framework reveals significant vulnerabilities in the American strategic position. First, the capacity for alliance mobilization — so critical to historical military success — is conspicuously absent.

Trump called on NATO partners to help secure the Strait of Hormuz, through which approximately 20% of the world's oil supply transits, but European NATO members, led by Germany, explicitly refused.

Germany's Defense Minister Boris Pistorius was direct in his rejection, stating that the conflict was "not our war" and questioning what European frigates could offer that the American Navy cannot manage independently.

Several other NATO countries went further, explicitly criticizing the American bombing campaign.

Second, the Iranian strategic response has demonstrated the adaptive resilience characteristic of states that have endured decades of sanctions, military threats, and proxy conflicts.

Iran's leadership, under a new Supreme Leader installed after the June 2025 conflict, has deployed a combination of short- and medium-range ballistic missiles and drone swarms designed to exhaust Israeli interceptor supplies and impose continuous economic costs, rather than seeking a single decisive engagement.

By March 2026, Iran had broadened its retaliatory strikes across 9 countries, dramatically expanding the conflict's geographic scope.

Third, the absence of a diplomatic exit — what strategists call an "off-ramp" — has allowed the war to metastasize rather than resolve.

The lack of a credible negotiated settlement framework means that even successful military strikes may fail to translate into durable strategic outcomes.

A war that damages Iran's nuclear infrastructure but fails to produce a stable post-conflict political arrangement risks repeating the Iraq pattern: tactical success without strategic resolution.

The Collapse of Alliance Solidarity: NATO's Existential Crisis

The fracturing of American alliance relationships is not limited to the Iran campaign.

It reflects a deeper structural transformation in the geopolitical landscape precipitated by the Trump administration's sustained assault on the assumptions undergirding the post-1945 liberal international order.

The Greenland crisis exemplifies this dynamic. President Trump's repeated demands that Denmark cede Greenland to the United States — accompanied by threats of economic tariffs and, implicitly, military coercion — has introduced a fundamental contradiction into the logic of the NATO alliance.

Article 5 of the NATO Treaty commits all members to collective defense against external aggression. Trump's threats against Denmark, a fellow NATO member, represent precisely the category of coercive behavior the alliance was designed to deter, applied now by its founding power against one of its own members.

Denmark's Prime Minister Mette Frederiksen stated explicitly that an American attack on Greenland would end NATO.

France, Italy, Poland, and the United Kingdom have formally expressed solidarity with Copenhagen. Greenland's own governing coalition has categorically rejected any American takeover under any circumstances.

The strategic implications are profound: the United States, for the first time in the alliance's history, is perceived by European partners not as the guarantor of collective security but as a potential threat to it.

This perception is reinforced by the cumulative effect of Trump's approach to NATO since his return to power in January 2025.

The American Defense Secretary's absence from the NATO defense ministers meeting in Brussels in February 2026, following the Secretary of State's absence from the NATO foreign ministers meeting in December 2025, signals a deliberate American disengagement from alliance management that European capitals interpret as abandonment.

The result is that Europe is accelerating its own rearmament, constructing what amounts to a parallel security architecture that does not depend on American leadership.

This process — the strategic decoupling of European security from American guarantees — is precisely the kind of alliance erosion that historically precedes major power shifts.

When alliance cohesion collapses, the collective deterrent capacity of the Western bloc diminishes, adversaries are emboldened, and the geopolitical landscape becomes more fluid and more dangerous.

The Strategic Logic of Victory in Asymmetric Environments

Winning Wars in the Twenty-First Century: Strategy, Legitimacy, and the Limits of Military Power

The contemporary landscape of conflict — characterized by drone warfare, information operations, economic sanctions, proxy networks, and hybrid strategies — demands a reconceptualization of what victory actually means.

The metrics of success that governed industrial-age warfare — territory captured, armies destroyed, capitals occupied — are insufficient guides to outcome in an era where conflict rarely ends in formal surrender.

In asymmetric conflicts, victory increasingly depends on a state's ability to shape the adversary's cost-benefit calculus rather than physically destroy its military capacity.

Iran has spent four decades developing precisely this kind of asymmetric deterrent: a network of proxy forces spanning Lebanon, Iraq, Yemen, Syria, and Gaza; a ballistic missile arsenal numbering in the thousands; drone swarms capable of saturating advanced air defense systems; and the demonstrated willingness to accept punishment without strategic capitulation.

Against such a strategic posture, the effectiveness of even a sustained air campaign is limited by the fundamental mismatch between the tools being applied and the objectives being sought.

Air power can degrade physical infrastructure, kill commanders, and disrupt supply chains. It cannot, by itself, change a state's political culture, ideological commitments, or survival instincts when regime survival has been identified with national survival.

The lesson of the Iraq War, Libya, and the earlier phases of the Syria conflict is that the destruction of an adversary's conventional military capacity can produce chaos rather than order, creating the conditions for proxy expansion rather than strategic resolution.

This is not to suggest that the United States cannot achieve important tactical objectives in the current campaign.

Significant degradation of Iranian nuclear infrastructure, if sustained, may set back Iran's weapons timeline by years.

Disruption of Iranian command networks and precision strikes on the Islamic Revolutionary Guard Corps leadership may temporarily degrade operational capacity.

But achieving these tactical gains while losing the alliance war — as the United States appears to be doing by alienating European partners and deepening perceptions of American unilateralism — is a formula that historical analysis identifies with strategic failure, even when tactical success is real.

Cause and Effect: How Today's Decisions Shape Tomorrow's Landscape

Who Wins Wars and Who Loses Them: Lessons from History for a Fractured World

The causal chains connecting current decisions to future strategic outcomes are already visible.

The American decision to pursue unilateral military action against Iran without multilateral authorization has produced a cascade of effects: European NATO members have not only refused to support the Iran campaign but are now publicly debating the utility of the alliance itself; China has identified an opportunity to present itself as a responsible stakeholder committed to diplomatic resolution while the United States deploys military force without UN Security Council authorization; and Iran's regional proxy networks, despite suffering significant degradation, have expanded their geographic reach in retaliation.

The Greenland imbroglio adds another causal dimension.

By treating a NATO ally as a potential territorial acquisition target, the Trump administration has accelerated the very process of European strategic autonomy that American strategists have historically sought to prevent.

A more autonomous European security architecture is not inherently incompatible with American interests.

Still, its emergence under conditions of mutual suspicion and strategic divergence creates coordination problems that adversaries will exploit.

The Iranian leadership, for its part, has demonstrated considerable strategic rationality in its response to the current campaign.

Rather than accepting the American-Israeli framework of a limited, surgical conflict aimed at nuclear disarmament, Tehran has consistently worked to internationalize the conflict, expand the geographic scope of retaliation, and impose costs on the broadest possible coalition of American partners.

By striking across nine countries, Iran forces every state in the region to calculate the costs of alignment with Washington and the potential benefits of neutrality or accommodation with Tehran.

Future Landscape: What Comes Next

Iran Under Fire, NATO in Crisis: How America's Wars Expose the Fractures of Its Alliances

The strategic trajectory of the current conjuncture points toward several possible futures, none of them stable in the near term.

The most optimistic scenario envisions a negotiated settlement of the Iran conflict that provides Tehran with security guarantees and graduated sanctions relief in exchange for verifiable nuclear disarmament and a halt to proxy sponsorship.

Such a scenario would require the Trump administration to accept a diplomatic outcome that it cannot frame as total victory — a significant political constraint given the administration's domestic narrative about the campaign.

A more likely near-term scenario is a continuation of the current campaign at sustained intensity, with Iran absorbing damage to its nuclear and military infrastructure while maintaining strategic deterrence through proxy networks and missile capabilities.

Under this scenario, the conflict neither produces a decisive American-Israeli victory nor Iranian capitulation.

Still, rather a prolonged attrition that erodes American credibility, deepens European estrangement, and gradually shifts the regional balance of influence.

The most dangerous scenario involves an Iranian decision to accelerate rather than abandon its nuclear program in response to the current strikes, reasoning that nuclear deterrence is the only reliable guarantee against regime change.

Several analysts at major security institutions have warned that sustained strikes on Iranian nuclear facilities may paradoxically accelerate Iranian nuclear weapons acquisition by demonstrating to the leadership that conventional deterrence is insufficient.

For NATO, the future is similarly fraught.

The combination of Trump's Greenland threats, his criticism of European allies for not joining the Iran campaign, and the symbolic absences from alliance ministerial meetings has created a crisis of confidence that purely rhetorical reassurances will be insufficient to repair.

European rearmament is accelerating, but the transition from an American-led to a European-led security architecture will take years and carry significant risks of gaps and miscalculations during the transition period.

The emerging global strategic landscape is one in which American primacy, while still real in material terms, is increasingly contested in political and institutional terms.

China has observed the unfolding American strategic difficulties with careful attention, and the lessons Beijing draws from Washington's experience — regarding the limits of air power, the fragility of alliances under unilateralist pressure, and the costs of legitimacy erosion — will shape Chinese strategic planning for a potential Taiwan contingency in ways that are not yet fully legible.

Conclusion: The Enduring Architecture of Victory and Defeat

Why Great Powers Lose Small Wars: History's Enduring Lesson for Washington, Moscow, and Beijing

The great lesson of strategic history is that wars are won not by those who strike hardest first but by those who endure longest, mobilize most effectively, maintain the broadest coalition, and sustain the legitimacy of their cause in the eyes of both their own population and the international community.

These determinants of victory are structural, not circumstantial. They operate across centuries and across the full spectrum of conflict from industrial war to asymmetric insurgency.

The United States today possesses extraordinary material military power. Its air forces, naval assets, intelligence capabilities, and precision munitions are unmatched by any single adversary.

Yet the structural conditions that have historically determined victory — alliance cohesion, domestic political consensus, international legitimacy, and strategic clarity of purpose — are all under severe strain.

The European allies who built Western strategic primacy alongside Washington are now questioning whether that partnership remains viable.

The alliance that defeated fascism, contained Soviet expansion, and managed the post-Cold War transition is fracturing under the pressure of unilateralism, territorial revisionism, and strategic narcissism.

Iran, for its part, has demonstrated the asymmetric resilience that historically characterizes states fighting for survival on their own territory.

It has absorbed significant military damage, adapted its command structure, expanded its retaliatory reach, and maintained domestic political control through the transition of supreme leadership.

Whether it can ultimately prevail against American-Israeli military power is uncertain. What is already clear is that it has avoided the rapid defeat that the campaign's architects likely envisioned.

The FAF analysis of who wins wars and why does not yield comfortable answers.

Victory belongs not to the powerful but to the strategically coherent — to those who align military means with political ends, sustain alliances under pressure, maintain domestic legitimacy, and adapt to the unpredictable dynamics of conflict with intelligence and discipline.

By that standard, the current American strategic position, notwithstanding its material dominance, exhibits the characteristic vulnerabilities of states that historical analysis identifies with strategic overreach.

The lessons are available to those willing to read and implement.
