US-UK orchestrated coup: The US and British governments overthrew Iran's democratically elected Prime Minister Mohammad Mosaddegh to install the Shah. "Don't forget that in 1953 we and the British government overthrew their elected government to install the Shah Pahlevi over what else? Oil."

Impact of the coup: This intervention is seen by many Users as the catalyst for lasting Iranian distrust of the U.S. and a foundational trauma in modern Iranian political memory. "The relationship with the US started to decline after the 1953 coup, which the US engineered to install the shah, ousting a democratically elected leader."

The Islamic Revolution and Its Aftermath

Shift to autocracy: The Shah's increasingly autocratic rule with US backing, following the 1953 coup, was a major factor leading to the 1979 revolution. "Later turning points matter enormously too, especially the shah’s increasingly autocratic rule with U.S. backing, the 1979 revolution, and above all the hostage crisis which turned distrust into open enmity."

Hostage crisis and severed ties: The 1979 hostage crisis, where Iranian students took over the US Embassy, led to economic sanctions and the severing of diplomatic relations. "The two countries have been particularly hostile to each other since Iranian students took over the U.S. Embassy in Tehran in November 1979, resulting in economic sanctions and the severing of formal diplomatic relations between the nations."

"Iran has not started a classic full-scale interstate war is more defensible. Iraq started the Iran-Iraq War in 1980. But that still does not justify pretending Iran has not pursued regional power projection, coercion and armed influence through allied militias and proxy networks in Lebanon, Iraq, Syria, Gaza and Yemen."

Nuclear ambitions: Iran's nuclear program and uranium enrichment are significant sources of tension with the US and its allies. "We're not building bombs, we're just enriching uranium to 60% for no reason.' -Iran"

Ongoing geopolitical struggle: The current dynamic is often viewed as a continuation of a broader geopolitical struggle, with Iran allied with Russia and opposing Western influence. "In the Middle East, Iran has functioned as one of Russia’s key partners for decades."
