Regime-change Architecture and Its Legacy

Twenty-five years after the 11 September 2001 attacks, the political map of the Middle East presents a pattern too persistent to dismiss as coincidence yet too varied to compress into a single doctrine. Iraq, Syria, Lebanon, Libya, Somalia, Sudan and Iran (hereafter, the ‘7-Cs’) – states with profoundly different histories, institutions and internal dynamics – nonetheless became arenas of invasion, regime collapse, civil war, sanctions, fragmentation or prolonged confrontation. Iraq was overthrown; Libya disintegrated; Syria internationalised; Lebanon repeatedly convulsed; Somalia and Sudan remained fractured; Iran endured as the most resilient adversary. The recurrence demands explanation, but the variation warns against simplistic narratives.

The intellectual roots of later regime-change thinking emerged after the Vietnam War, when Washington reassessed how American power could be exercised without repeating Vietnam’s costs and constraints. What followed was not a continuous doctrine but an evolution from restoring American credibility and countering Soviet influence to exercising greater freedom of action after the Soviet collapse. By the 1990s, attention increasingly shifted toward hostile Middle Eastern governments.

The seven-country sequence entered public discussion through retired General Wesley Clark, who recalled a Pentagon memorandum contemplating action against the ‘7-Cs’. The significance of his account lies less in whether a literal checklist was executed than in whether it reflected a strategic worldview that persisted across administrations. A Clean Break, prepared in 1996 for Benjamin Netanyahu by a study group led by Richard Perle, was not an American war plan, but it showed that influential strategists were already debating how weakening hostile governments could reshape regional balances.

What followed is better understood as an evolving strategic architecture rather than a mechanically executed blueprint. A blueprint prescribes sequence; while an architecture establishes the structural environment within which successive administrations may still move in similar directions. The architecture did not dictate identical outcomes; instead, it created a field in which governments repeatedly found themselves at the intersection of American, Israeli, regional and global interests.

Regime change is not governed by military strength alone but by interacting variables: military vulnerability, institutional resilience, domestic legitimacy, economic structure, ethnic and sectarian composition, external sponsorship, geography, historical memory and the availability of a credible successor. A regime may be militarily weak yet politically durable, or militarily strong yet institutionally brittle. Pressure on one dimension may strengthen another through nationalism or consolidation. External intervention may destroy state capacity without producing legitimacy. Regime change is therefore a systems problem, not merely a military event.

Iraq demonstrated how military victory could outrun political reconstruction. The 2003 invasion removed Saddam Hussein, but the successor order struggled with legitimacy, coherence and security capacity. Libya followed another path. NATO’s 2011 intervention contributed to the removal of Muammar Gaddafi, yet the collapse of the state exposed the absence of institutions capable of preventing fragmentation. In both cases, overwhelming force destroyed governments without guaranteeing viable successors. Iraq and Libya thus reveal distinct failures: reconstruction lagged behind military victory in one, while institutional collapse preceded political consolidation in the other.

Syria, Lebanon, Somalia and Sudan complicate the pattern and, precisely for that reason, strengthen the argument against a simplistic ”7-Cs” blueprint. Washington did not invade Syria, but after the 2011 uprising became a civil war, the US supported opposition forces, imposed sanctions and called for Bashar al-Assad to leave power, while Russia, Iran, Türkiye, Gulf states and Israel transformed Syria into an arena of competing strategic interests. Lebanon became inseparable from the Israel-Hezbollah confrontation. Somalia’s instability long predated 9/11 and American involvement centred mainly on counterterrorism. Sudan’s partition and recurrent conflicts arose from deep domestic, ethnic, political and economic forces. Their inclusion shows that the sequence was never seven identical regime-change operations; each entered the wider strategic contest through a different configuration of internal weakness, external pressure and geopolitical rivalry.

Iran is the inverse case and the most consequential test of the architecture. Despite 47 years of sanctions, covert confrontation, political pressure and military threats, Tehran avoided the political collapse experienced by Iraq or Libya. It developed missiles, drones, dispersed infrastructure, regional relationships and asymmetric capabilities designed to preserve retaliatory capacity against militarily superior adversaries. In Matrix terms, military vulnerability coexists with institutional depth, geographic advantage and the ability to impose costs beyond the battlefield. A weaker state need not match an adversary aircraft for aircraft or ship for ship if it can threaten shipping lanes, energy flows, regional bases and allied economic interests. Iran therefore raises the larger question of whether conventional superiority can still be converted into decisive political outcomes when asymmetric deterrence widens the field of vulnerability.

Columbia University economist Jeffrey Sachs has revived Clark’s account by linking it to A Clean Break and to the subsequent history of American and Israeli policy. Several of the seven countries resisted Israeli regional dominance, supported Palestinian organisations, backed Hezbollah or otherwise challenged the strategic order preferred by Washington and Jerusalem. Those connections matter, but they do not explain all seven cases equally well. Libya, Somalia and Sudan fit the proposition less comfortably; Iraq involved post 9/11 doctrine, intelligence failures, neoconservative ambitions, geopolitical calculations and domestic politics; Syria began with a domestic revolt before becoming internationalised. Palestine therefore belongs within the matrix but cannot bear the explanatory burden alone. Regional primacy, alliances, energy security, ideological rivalry and domestic state weakness also shaped the architecture.

Twenty-five years later, history has supplied both a political and a fiscal ledger.  US federal debt has crossed $40 trillion. Middle Eastern wars did not create that burden by themselves: tax policy, entitlement spending, pandemic expenditures, mounting interest costs on the burgeoning debt and persistent deficits account for enormous portions of its growth. Yet the architecture of regime change due to its open-ended commitments, dispersed obligations, inherited deployments and institutional momentum structurally predisposes the US to long-duration expenditures that outlive the political decisions that initiated them. Wars, occupations, counterterrorism campaigns and an expanding national-security apparatus consumed vast resources while generating obligations extending far beyond the battlefield. Governments were overthrown, states fragmented and commitments multiplied, while the promise that superior power could readily translate into stable political outcomes repeatedly proved elusive.

The confrontation with Iran may now be exposing the architecture’s most important limitation. Rather than reinforcing a unipolar regional order, sustained pressure is encouraging strategic diversification, deeper non-Western relationships and movement toward a more multipolar system in which weaker states increasingly rely on asymmetric strategies to constrain stronger ones. Nearly seven months of on-again, off-again confrontation have not produced the swift political outcome that overwhelming military superiority might once have suggested. The US instead confronts a strategic environment in which escalation carries military, economic and geopolitical costs across several dimensions simultaneously.
