From Weimar to Tehran: How Divided Democracies Face Long-Term Challenges
“Boxing with a Knife” – Asymmetry and the Strategic Dilemma for Divided Democracies
March 08th, 2026
Berlin Global’s Sunday Article – For much of the post-World War II era, Western democracies have understood themselves as bastions of stable institutions, predictable diplomacy and rule-based international order. Yet today they confront a profoundly different kind of challenge: a regional power that combines ideological ambition, asymmetric warfare, proxy networks, nuclear brinkmanship and influence operations, while Western societies remain internally fractured, politically polarized and constrained by short electoral cycles.
The Strategic Problem: Asymmetry Meets Fragile Democracies
Since the revolution of 1979, Iran has pursued a foreign policy that at times diverges from established international norms, supporting proxy groups across the Middle East, challenging U.S. and allied interests and advancing a nuclear enrichment program that has repeatedly brought it into tension with Western powers and the United Nations. These dynamics culminated in a major regional escalation in 2025-26 that saw direct military engagements and heightened concerns about broader conflict.
At the same time, Western democracies, including the United States and the European Union, are deeply divided internally. Fragmented political landscapes, frequent elections and competing domestic priorities make sustained long-term strategy difficult. Leaders are wary of action that could prove unpopular at home or provoke backlash at the ballot box a factor that external actors can exploit.
The result is a strategic asymmetry: one side operates with a long-term, risk-tolerant approach while the other must constantly navigate internal dissent, changing governments and public opinion. As William L. Shirer described in The Rise and Fall of the Third Reich, political fragmentation and indecision in Weimar Germany allowed a determined and norm-defying political force to consolidate power and expand unchecked. Alexis de Tocqueville in Democracy in America similarly noted that democratic societies are inherently open and pluralistic, which is a strength under normal circumstances but can create vulnerabilities when faced with disciplined, patient actors willing to exploit divisions and slow decision-making.
Iran’s Multi-Front Strategy
Iran’s approach combines multiple elements that make it a complex strategic counterpart. Tehran has cultivated networks of allied armed groups, including Hezbollah, militias in Iraq, and the Houthis, allowing it to project influence indirectly and complicate conventional military responses. Its nuclear program has alternated between negotiation and escalation: the 2015 Joint Comprehensive Plan of Action (JCPOA) initially limited enrichment, but following the U.S. withdrawal, Tehran expanded activities significantly. While it has not declared a weapon, enriched uranium stockpiles and advanced facilities have raised international concern, and the “breakout time” for potential weapons development has periodically narrowed. Domestically, significant restrictions on dissent and strong state control of information allow the leadership to frame external pressure as interference, reinforcing cohesion even amid economic challenges. Beyond these measures, Iran engages in efforts to shape international narratives through media and political discourse. As Carl von Clausewitz emphasized in On War, understanding an opponent’s political and informational leverage is as crucial as assessing their military capabilities an insight highly relevant to these hybrid strategies.
“Boxing with a Knife”: The Asymmetric Challenge
The metaphor “boxing with a knife” captures the asymmetry in strategic approaches. In a conventional boxing match, both participants follow the same rules. If one introduces a fundamentally different method, the nature of the contest changes.
In the international arena, democracies often operate within legal frameworks, treaties, and norms. Other actors, including Iran, may at times employ a broader range of tools, including indirect and unconventional methods, which do not always align with those frameworks.
The lesson is not that democracies should abandon their principles, but that they may need to adapt their strategies. Long-term, multi-layered approaches that combine deterrence, alliances, societal resilience and cultural diplomacy can help address such asymmetries while preserving core values.
The Democratic Challenge: Polarization and Short-Termism
Western democracies face structural constraints in sustaining long-term strategic engagement:
Short electoral cycles mean that leadership changes frequently and policy continuity can be difficult to maintain. As Barbara W. Tuchman illustrated in The Guns of August, short-term political calculations and failure to anticipate escalation can contribute to serious misjudgements.
Fragmented politics and media environments complicate unified messaging and can leave space for external narratives to resonate. Open information systems are both a strength and a vulnerability.
Multilateral structures, including the European Union, often require consensus, which can slow coordinated responses. A. J. P. Taylor argued in The Origins of the Second World War that hesitation and fragmentation can allow determined actors to expand their influence before responses are fully mobilised.
These characteristics echo earlier periods in which democracies struggled to respond cohesively to sustained external challenges.
Lessons From History and What They Suggest for Today
Historically, democracies have demonstrated resilience when they develop long-term strategies and institutional continuity beyond electoral cycles.
During the Cold War, alliances such as NATO and broader containment strategies provided stability across changing governments. Edward N. Luttwak, in The Grand Strategy of the Roman Empire, emphasised the importance of long-term, multi-layered planning.
Public resilience also plays a role. Investment in media literacy, transparent institutions and civic education can reduce the impact of external influence efforts. Tocqueville’s observations remain relevant in highlighting both the strengths and vulnerabilities of open societies.
Clear policy frameworks and coordinated deterrence, when supported by multiple states, can enhance credibility and reduce uncertainty.
In the case of Iran, these lessons suggest that a combination of sustained diplomatic engagement, deterrence and internal resilience may help manage tensions and reduce the risk of escalation.
The Urgency of Strategy in a Divided World
The strengths of democratic systems openness, pluralism and institutional checks can also create challenges in responding quickly and coherently to complex external pressures. Iran’s combination of regional influence, nuclear development, governance model and information efforts present a multifaceted strategic environment.
At the same time, history indicates that democracies are capable of responding effectively when they develop long-term consensus and align their strategies across political cycles. The works of Shirer, Taylor, Clausewitz, Tuchman and Tocqueville all point to the importance of institutional continuity, strategic patience and clear understanding of the broader context.
Historical Comparison: Weimar Germany and Lessons for Today
The challenges faced by the Weimar Republic between 1919 and 1933 illustrate how political fragmentation and instability can weaken democratic systems. Economic crises, competing political factions and short-lived governments created conditions in which a disciplined and ideologically driven movement was able to consolidate power.
As William L. Shirer observed, underestimation, fragmentation and short-term thinking contributed significantly to the collapse of democratic governance.
The comparison is not direct, but it highlights a broader lesson: when democracies face sustained external pressure while internally divided, maintaining coherence and long-term strategy becomes essential.
The West and the Soviet Union: Containment Without Direct War
After 1945, Western democracies faced the Soviet Union, another long-term strategic competitor. Rather than immediate confrontation, they developed a strategy of containment, combining economic, political and military tools.
The Marshall Plan, NATO, and diplomatic coordination created a framework that endured across decades. This approach allowed the West to manage competition while avoiding large-scale war.
The lesson is that sustained, coordinated strategy rather than reactive or fragmented responses can provide stability even in prolonged periods of tension.
Cultural Diplomacy: Winning Influence Without War
During the Cold War, cultural diplomacy played an important role alongside military and economic strategy. Educational exchanges, artistic programmes and public diplomacy helped communicate the values of open societies.
These efforts strengthened alliances, countered competing narratives and contributed to long-term influence. Tocqueville’s insights underline how openness and civic engagement can serve not only domestic stability but also international credibility.
Applied today, such approaches can complement policy responses by reinforcing resilience, reducing polarisation and supporting informed public discourse.
Shared Responsibility and Strategic Continuity
Long-term stability cannot rest solely on adaptation by democracies; it also depends on reciprocal commitments, credible diplomacy, and sustained engagement by all actors involved. History shows that patient, coordinated, and multi-layered strategies combining deterrence, alliances, societal resilience and cultural diplomacy remain the most effective means of managing long-term challenges while upholding democratic principles.
The devastating world wars of the twentieth century led to a structural shift in the international order. The United Nations Charter codified a fundamental prohibition on the use of force permitting it only in self-defence against an armed attack or with Security Council authorisation. This inversion from recognising war as lawful if justified to forbidding war unless exceptions are met derives from the cumulative philosophical movement that sought to limit violence and embed it within legal constraints. Grotius’s core criteria of necessity, proportionality and imminence remain embedded in modern law even as legal structures now operate under precise treaty obligations.
Contemporary Case: The Iran-US-Israel Conflict
The current Middle Eastern conflict involving Iran, Israel and the United States highlights the enduring tension between state security concerns and the legal and moral restraints on force. On 28 February 2026, Israel and the United States launched a coordinated military offensive against targets in Iran, codenamed Operation Lion’s Roar by Israeli authorities and Operation Epic Fury by the United States Department of Defense. This campaign involved extensive air strikes on Iranian military infrastructure, ballistic missile capabilities and leadership targets, and reportedly resulted in the death of Iran’s Supreme Leader Ayatollah Ali Khamenei. The objective articulated by United States and Israeli leaders was to neutralise perceived threats stemming from Iran’s missile programmes and its alleged pursuit of nuclear weapons which they characterised as imminent dangers to regional and global security.
The attacks triggered immediate and widespread retaliation from Iran with ballistic missile and drone strikes directed at Israeli territory and United States forces in the Gulf region. The conflict has spread beyond Iran and Israel drawing in allied militias such as Iran-aligned Hezbollah in Lebanon and affecting multiple Gulf states diplomatically and militarily. Airspace closures and disruption of global supply routes, particularly through the Strait of Hormuz, have added economic and geopolitical dimensions to the crisis. Officials in Washington defended the strikes as necessary to pre-empt threats and prevent Iran from acquiring capabilities that could be used against Israel, the United States or their allies while military leaders framed the campaign as targeted and finite. Nonetheless critics including legal scholars and bodies such as the International Commission of Jurists condemned the operation as a violation of international law arguing that the charter’s strict prohibition on the use of force cannot be circumvented by claims of anticipated future risk in the absence of an armed attack or Security Council mandate.
This episode reflects a central philosophical tension whether a profound strategic threat can legitimately justify force in advance of actual aggression. Grotius and Vattel would likely have emphasised the necessity of imminence rather than speculative danger echoing concerns that preventive war undermines the very international order that law seeks to preserve. Modern doctrine shaped by Wheaton’s and Oppenheim’s refinements and codified in the UN Charter would similarly require unmistakable evidence of an imminent armed attack to legitimise such actions under international law.
Conclusion: Continuity and Challenge in the Theory of Force
The intellectual tradition from Grotius through Vattel, Wheaton and Oppenheim to the UN Charter demonstrates a long-standing effort to reconcile the security needs of states with moral and legal limits on the use of force. These thinkers consistently emphasised that military action must meet strict conditions of necessity, proportionality and immediacy. Grotius insisted that only an imminent and unavoidable threat could justify defensive action. Vattel reinforced this by stressing the importance of respecting the sovereignty of other states. Wheaton translated these ideas into concrete criteria that could guide diplomacy and state practice. Oppenheim narrowed the legal scope of permissible force and highlighted the risks that speculative preventive war posed to international stability.
The UN Charter codified these principles into binding law marking a profound shift from earlier eras in which war was permissible if justified by moral reasoning or political prudence. Today, these centuries of philosophical and legal reflection remain relevant because they offer a framework for evaluating the legitimacy of state action especially in crises that involve complex threats and the potential for large-scale destruction.
The current conflict involving Iran, Israel and the United States illustrates the enduring tension between perceived security threats and the obligations imposed by international law and moral reasoning. Claims of pre-emptive action to neutralise a future threat must be measured against the established principles of imminence, necessity and proportionality. If action is taken on the basis of speculation rather than immediate danger it risks undermining the very international order that these intellectual traditions sought to protect. This tension demonstrates that the lessons of the past are not abstract they remain critical for assessing modern conflicts and guiding state behaviour in a way that preserves peace, legitimacy and the rule of law.
Ultimately, the evolution of thought from Grotius to the UN Charter shows that the moral and legal frameworks governing war are cumulative. They are built on centuries of reflection about the proper limits of force, the duties of states and the consequences of unchecked violence. In applying these lessons to contemporary conflicts, policymakers and scholars are called to weigh not only the immediate tactical gains of military action but also the long-term consequences for international order, regional stability and the moral authority of the state. The principles articulated by these thinkers provide a rigorous lens for evaluating modern disputes and for ensuring that decisions about force are guided by both reason and law.
