The Shah’s power was tainted by foreign intervention: his father's British-backed coup and his own ascension after the British forced his father to abdicate. This narrative of being a foreign puppet permanently undermined his domestic legitimacy and was exploited by his opponents.

Young Iranians, with no memory of the Shah's era, embrace a romanticized vision of pre-1979 Iran's social freedoms and global standing. This nostalgia, combined with the regime's suppression of internal leaders, has elevated Reza Pahlavi as a symbolic, default leader for a nationalist reclamation.

The U.S. ambassador in 1977 was shocked that few staff spoke Farsi or had ever left Tehran. This linguistic and cultural isolation meant they lacked links to opposition groups, and their intelligence was based almost solely on the Shah's insulated royal court.

The Iranian Revolution was fueled by a Shia worldview centered on martyrdom, cosmic struggle between good and evil, and an apocalyptic final battle. U.S. policymakers, lacking any understanding of this religious framework, were completely unprepared for its political power.

The U.S. Embassy and CIA were unaware that the Shah was dying of leukemia, dismissing rumors as Russian propaganda. This critical intelligence gap meant they couldn't understand his indecisiveness and erratic behavior as the crisis escalated, misreading the entire situation.

Reza Pahlavi's strategy is not based on domestic uprising alone. He believes protestors are "sacrificial lambs" who cannot succeed without direct American military intervention, framing them as a "fort waiting for the cavalry." This dependence makes his plan vulnerable to US political shifts.

The Shah’s modernization efforts, including land reform and expanded state education, were intended to build popular support. Instead, they backfired by threatening the economic base and social authority of the powerful clerical class, turning them into organized opponents.

The Shah's shy, anxious personality, a product of his overbearing military father, made him susceptible to a personality cult. This detachment from reality, coupled with a Westernized worldview, prevented him from understanding the deep-seated grievances of his people.

Dara Khosrowshahi theorizes the Shah of Iran's regime collapsed because he modernized too fast, focused excessively on military power over industrial growth, and failed to bring along rural populations and integrate Islam into his vision, creating a power vacuum for the Islamic regime to exploit.
