What Trump Didn’t Know About Iran

What It Covers

Ezra Klein interviews Ali Vaez, Iran Project Director at the International Crisis Group and nuclear scientist, tracing the 47-year history of US-Iran hostility from the 1953 CIA-backed coup through the 1979 revolution, Iran-Iraq war, JCPOA negotiations, and the current military conflict — arguing the war began without a coherent American strategy or understanding of Iranian history.

Key Questions Answered

• •Nuclear breakout timeline collapse: The JCPOA kept Iran's nuclear breakout time — the period needed to enrich enough uranium for one weapon — above 12 months when Trump left the deal in 2018. By January 2025, that timeline had collapsed to six days. Iran now holds nearly half a ton of 60%-enriched uranium, sufficient for 10 nuclear warheads or four Hiroshima-scale devices. Weaponization still requires 6–12 additional months but can occur in secret, unmonitored facilities.
• •Maximum pressure backfired structurally: The Trump administration's maximum pressure campaign, articulated by Secretary Pompeo as forcing Iran to choose between feeding its people or funding proxies, produced the opposite of its intended effect. It decimated Iran's middle class — previously around 65% of society and described as the West's most viable internal ally — while strengthening the Revolutionary Guards. Iran's nuclear program, proxy networks, and domestic repression all accelerated during this period rather than contracting.
• •Proxy strategy born from 1980–88 war: Iran's doctrine of maintaining armed proxies across Lebanon, Gaza, Syria, and Iraq originated directly from the Iran-Iraq war, when Iran fought essentially alone against Saddam Hussein, backed by Gulf states, Western powers, and the Soviet Union. That experience of strategic isolation produced a calculated decision to build deterrence far from Iranian borders. Understanding this origin reframes proxy support not as ideological aggression but as a security architecture built from a specific historical trauma.
• •Hardliner feedback loop across all sides: Every attempt at Iranian moderation — Khatami's reformist presidency in 1997, Rouhani's nuclear deal in 2015 — ended with moderates discredited and hard-liners empowered, partly because the US failed to deliver on commitments. The pattern runs in both directions: US and Israeli pressure consistently strengthens Iranian hard-liners, while Iranian provocations strengthen hawkish factions in Washington and Tel Aviv. Recognizing this cycle is prerequisite to breaking it rather than accelerating it.
• •Soleimani's assassination created proxy freelancing: The 2020 killing of IRGC Quds Force commander Qasem Soleimani removed the one figure with personal relationships and sufficient authority to coordinate and restrain Iran's network of regional proxies. His absence created space for actors like Hamas leader Sinwar to operate independently. Iran had concluded in April 2023 that its "ring of fire" strategy — opening four simultaneous fronts against Israel — was not yet ready, but lacked the command structure to communicate that restraint to Sinwar before October 7.
• •1953 coup shapes every subsequent negotiation: The US-UK orchestrated removal of Prime Minister Mosaddegh in 1953 is taught to every Iranian schoolchild and functions as a foundational grievance absent from American institutional memory. This asymmetry in historical awareness directly affects negotiations: Iranian officials interpret US demands through the lens of a country that previously installed and removed their leaders, making capitulation existentially threatening to regime legitimacy. Any diplomatic framework that ignores this asymmetry will misread Iranian red lines and negotiating constraints.
• •Post-war scenarios all carry compounding risks: If the current conflict ends with the regime surviving under Khamenei's son, Iran retains its enriched uranium stockpile and gains a leadership likely more committed to weaponization than his father. If the regime collapses without an organized opposition — no group currently has ground-level organizational capacity — the result resembles post-Gaddafi Libya or post-2003 Iraq: factional fragmentation, refugee crises, and regional destabilization. A negotiated ceasefire followed by incremental deal-making represents the only pathway that avoids both outcomes.
