Trump's demand for a role in selecting Iran's supreme leader echoes a pattern of U.S. regime engineering that has failed spectacularly for seven decades
Executive Summary
- Trump's declaration that the U.S. "must be involved" in choosing Iran's next supreme leader marks the most explicit American claim to dictate another nation's leadership since Iraq 2003 — a venture that cost $2 trillion and 4,500 American lives.
- The historical record is devastating: Of seven major U.S. regime change operations since 1953, only one (Panama 1989) produced a stable, democratic outcome within a decade. The original sin — Iran 1953 — created the very theocracy Washington now seeks to dismantle.
- The succession crisis creates a three-way power struggle between Mojtaba Khamenei (whom Trump dismissed as "a lightweight"), IRGC hardliners seeking a military strongman, and reformist elements hoping for a negotiated transition — with American interference likely to strengthen the most anti-Western faction.
Chapter 1: The Kingmaker's Claim
On March 5, 2026 — Day 6 of Operation Epic Fury — President Trump told Axios that the United States "must be involved" in selecting Iran's next supreme leader. He dismissed Mojtaba Khamenei, the 56-year-old son of the assassinated Ayatollah Ali Khamenei and the Assembly of Experts' frontrunner, as "a lightweight." Trump declared: "We want someone that will bring harmony and peace to Iran."
Hours later, at the White House, Trump urged Iranians to "help take back your country," promising "total immunity" to those who cooperated — without specifying what that meant. Defense Secretary Pete Hegseth warned that American firepower over Tehran was "about to surge dramatically."
The juxtaposition is striking. A president who campaigned in 2016 against nation-building — "We must abandon the failed policy of nation building and regime change" — and who in 2025 in Riyadh mocked interventionists for meddling "in complex societies that they did not even understand," is now claiming the right to select the leader of a nation of 88 million people, with a civilization stretching back millennia.
This is not just rhetoric. It represents a fundamental strategic shift from the administration's stated war aims of "denuclearization and defanging" to something far more ambitious and historically perilous: regime engineering.
Chapter 2: The Graveyard of Kingmakers — Seven Decades of Failure
America's track record of installing or selecting foreign leaders is among the most consistently disastrous patterns in modern geopolitical history. Each case offers lessons directly applicable to Iran 2026.
Iran 1953: The Original Sin
The CIA's Operation Ajax overthrew democratically elected Prime Minister Mohammad Mosaddegh and restored Shah Mohammad Reza Pahlavi to near-absolute power. The immediate result was favorable to Washington: a compliant ally who opened Iran's oil to Western companies and served as a Cold War bulwark.
The long-term consequence was catastrophic. Twenty-six years of increasingly authoritarian rule bred exactly the revolutionary fervor that produced the 1979 Islamic Revolution — the very theocratic system the U.S. is now bombing. The historical irony is almost too perfect: America's last attempt to choose Iran's leader created the regime it is now trying to destroy.
Time from installation to blowback: 26 years.
Iraq 2003: The $2 Trillion Lesson
The U.S. toppled Saddam Hussein with overwhelming force in three weeks. The subsequent occupation lasted eight years, cost over $2 trillion, killed 4,431 American service members and an estimated 200,000+ Iraqi civilians, and produced a fractured state that spawned ISIS. The U.S.-backed government in Baghdad tilted toward Iran — the very adversary Washington sought to contain.
Key parallel to Iran 2026: Iraq had 26 million people at invasion. Iran has 88 million — 3.4 times larger — with far more mountainous, defensible terrain.
Afghanistan 2001-2021: The 20-Year Occupation
The longest war in American history produced a government so dependent on U.S. support that it collapsed in 11 days when American forces withdrew. The Taliban returned to power, and $2.3 trillion in spending evaporated overnight.
Libya 2011: Regime Change Without a Plan
NATO air power helped topple Muammar Gaddafi. With no postwar plan, Libya fractured into warring fiefdoms, became a migrant crisis epicenter, and remains ungoverned 15 years later. President Obama later called the failure to plan for post-Gaddafi Libya the "worst mistake" of his presidency.
The Scorecard
| Operation | Year | Target Pop. | Initial Success | 10-Year Outcome | Cost (est.) |
|---|---|---|---|---|---|
| Iran (Ajax) | 1953 | 18M | Yes | Authoritarian ally → Revolution | $10M (CIA) |
| Vietnam | 1963 | 35M | Mixed | Communist reunification | $850B |
| Chile | 1973 | 10M | Yes | 17-yr dictatorship | Unknown |
| Panama | 1989 | 2.5M | Yes | Stable democracy | $660M |
| Iraq | 2003 | 26M | Yes | Civil war, ISIS, Iran influence | $2T+ |
| Libya | 2011 | 6.4M | Yes | State collapse | $1.1B |
| Afghanistan | 2001 | 28M | Yes | Taliban return after 20 years | $2.3T |
Success rate for stable democratic outcome: 1 out of 7 (14%).
Panama, the sole success, had 2.5 million people. Iran has 88 million.
Chapter 3: Why Iran Is Uniquely Resistant to External Kingmaking
The Nationalism Factor
Iran possesses something most U.S. regime change targets lacked: a deep, ancient national identity predating Islam by over a millennium. Persian civilization stretches back 2,500 years. Even Iranians who despise the Islamic Republic rally against foreign interference — the January 2026 crackdown killed thousands of protesters, yet those same protesters overwhelmingly reject American-imposed leadership.
Polling by the Center for International and Security Studies at Maryland (CISSM) consistently showed that even among Iranians who supported the 2022-2023 Mahsa Amini protests, over 70% opposed foreign military intervention. The act of bombing a country while claiming to choose its leader does not generate the compliance Washington imagines.
The IRGC Factor
The Islamic Revolutionary Guard Corps controls an estimated 25-40% of Iran's economy through its vast network of construction, telecommunications, and energy companies. It employs hundreds of thousands directly and supports millions of dependents. The IRGC is not merely a military force — it is an economic empire with deep roots in Iranian society.
Any American-backed leader would need to either co-opt or confront this structure. The shah's SAVAK secret police was a fraction of the IRGC's institutional footprint. Dismantling it — as the U.S. attempted with Iraq's Ba'ath Party through "de-Ba'athification" — would create the same power vacuum that fueled the Iraqi insurgency.
The Geography Factor
Iran covers 1.65 million square kilometers — roughly the size of Alaska — with terrain ranging from the Zagros mountain chain to the Dasht-e Kavir desert. Iraq's relatively flat Mesopotamian plain allowed rapid U.S. armored advances. Iran's topography has defeated invaders from Alexander the Great to Saddam Hussein, whose eight-year war (1980-1988) failed to permanently capture a single Iranian city.
Chapter 4: The Succession Chess Game — Three Scenarios
The Assembly of Experts, an 88-member elected body of senior clerics, holds constitutional authority to select the next supreme leader. Trump's declaration effectively injects a hostile external variable into an already volatile internal process.
Scenario A: Mojtaba Prevails Despite Trump's Opposition (45%)
Rationale: The Assembly of Experts has already convened in emergency session. Mojtaba Khamenei has spent years cultivating relationships within the clerical establishment and reportedly has IRGC Quds Force support. Trump's public dismissal of him as "a lightweight" may paradoxically strengthen his candidacy by framing him as the anti-American choice.
Historical precedent: When the U.S. publicly opposed Hamas in the 2006 Palestinian elections, Hamas won in a landslide. American opposition became a campaign asset.
Trigger conditions: Assembly convenes within days, fast-tracks Mojtaba before external pressure can organize alternatives. IRGC provides security guarantees.
Investment implication: Prolonged confrontation. No diplomatic off-ramp. Oil remains above $80 for months. Defense spending acceleration continues.
Scenario B: IRGC Military Strongman Emerges (30%)
Rationale: With the supreme leader dead and much of the senior clerical leadership killed or in hiding, the IRGC may conclude that a cleric lacks the authority to navigate wartime. A military-clerical hybrid figure — perhaps someone like Rear Admiral Ali Shamkhani (former SNSC secretary) or a surviving IRGC commander — could emerge as a "wartime leader."
Historical precedent: Egypt's 1952 Free Officers revolution, where military officers displaced a dysfunctional monarchy. Also, Pakistan's repeated military coups during national crises.
Trigger conditions: Continued strikes decapitate enough clerical leadership that the Assembly cannot form a quorum. IRGC declares emergency authority.
Investment implication: Military government likely more aggressive in short term (rally-around-flag) but potentially more pragmatic on negotiations medium-term. Oil volatility spikes, then gradually moderates.
Scenario C: Negotiated Transition with Western Input (25%)
Rationale: This is Trump's stated preference. It would require reformist elements within Iran's government — possibly connected to former Foreign Minister Javad Zarif or figures around President Pezeshkian — to gain enough support to negotiate.
Historical precedent: South Africa's negotiated transition (1990-1994), where international pressure combined with internal reformers produced a managed handover. However, South Africa was not being actively bombed during negotiations.
Trigger conditions: Sustained military pressure makes continuation untenable. IRGC leadership fractures. Back-channel communication (possibly through China's Zai Jun envoy or Oman) produces framework. Ceasefire precedes negotiations.
Investment implication: Best-case scenario for markets. Risk premium reversal. Oil could fall 20-30% on ceasefire news. But probability is lowest because it requires the most variables to align simultaneously.
Critical risk across all scenarios: Trump's public claim to "choose" Iran's leader poisons the well for any Iranian figure who might cooperate with Washington. In a society traumatized by 1953, being labeled "America's choice" is political — and possibly literal — death.
Chapter 5: Market Implications and Investment Positioning
The Regime Change Premium
Markets are pricing in conflict continuation, not regime engineering. If Trump's rhetoric escalates from "denuclearization" to active regime change, the risk premium expands significantly:
| Asset | Current Level | Regime Change Scenario | De-escalation Scenario |
|---|---|---|---|
| Brent Crude | ~$85/bbl | $100-120/bbl | $65-70/bbl |
| Gold | ~$5,100/oz | $5,500-6,000/oz | $4,800/oz |
| DXY (Dollar) | Elevated | Further strength | Moderate pullback |
| S&P 500 | 6,831 | 6,200-6,500 | 7,200+ |
| 10Y Treasury | Rising | 5%+ (stagflation fear) | 4.2-4.5% |
The Iraq Analogy in Markets
When the U.S. invaded Iraq in March 2003, the S&P 500 initially rallied 15% over two months on "mission accomplished" optimism. It then gave back most gains as the occupation's true costs became apparent. The war ultimately cost 0.7% of U.S. GDP annually for eight years.
An Iran regime engineering effort at comparable GDP share would cost approximately $200 billion annually — in an economy already strained by war spending, tariff inflation, and AI infrastructure investment.
Sectors to Watch
Beneficiaries of prolonged engagement: Lockheed Martin (LMT), RTX, Northrop Grumman (NOC), L3Harris — defense primes with backlog visibility. Also Halliburton (HAL), Baker Hughes (BKR) if occupation/reconstruction materializes.
Vulnerable: Airlines (fuel costs), consumer discretionary (stagflation squeeze), emerging market importers (energy dependence).
Conclusion: The Hubris Loop
There is a recurring pattern in American foreign policy that scholars call the "hubris loop": overwhelming military success in the initial phase creates the illusion that political engineering will be equally straightforward. Every regime change operation since 1953 has followed this trajectory — swift military victory, followed by political quagmire.
Trump's claim to choose Iran's next leader is not merely a diplomatic provocation. It is a strategic signal that the war's objectives may be expanding beyond what any military campaign can deliver. The $2 trillion lessons of Iraq and Afghanistan suggest that destroying a regime is orders of magnitude easier than building what comes after.
For investors, the critical variable is no longer the military campaign — which the U.S. and Israel are clearly winning — but the political aftermath. And on that front, history offers a blunt warning: the kingmaker rarely gets the king he wants.
