Islamic jurisprudence resolves contradictions in the Quran by giving precedence to later, more militant verses revealed in Medina when Muhammad was powerful. This principle of abrogation effectively nullifies the earlier, more peaceful Meccan verses.

A key theological distinction is that Old Testament violence is descriptive, recounting historical conflicts against specific, now-extinct peoples. In contrast, the Quran's calls to violence are prescriptive and open-ended, targeting the generic category of 'the infidel.'

While appearing as a traditionalist, Khomeini's core concept, the "Guardianship of the Jurist," was a profound theological revolution. It proposed for the first time that clerics should directly rule the state, breaking with centuries of Shiite political quietism. This innovation provided the ideological basis for the new republic.

The literal meaning of jihad as 'struggle' extends beyond warfare to include non-violent methods to advance Islam's influence. These include 'jihad of the tongue' (propaganda), financial influence, and demographic competition ('baby jihad').

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 Islamic Revolution in Iran provided a powerful and enduring model for political Islam. Its legacy, including the hostage crisis, shaped the American perception of the Middle East and global politics more profoundly than Communism did in the 21st century.

The vast majority of lands now considered the 'Muslim world,' including North Africa and the Middle East, were historically Christian territories taken by military conquest (jihad). The West often overlooks this long history of religiously motivated expansionism.

A core Islamic doctrine, 'Al-Wala' Wal-Bara'' (Loyalty and Enmity), commands Muslims to be loyal only to fellow Muslims and to harbor hatred and disavowal towards all non-Muslims. This creates a foundational 'us vs. them' worldview.

Ayatollah Khamenei believes that any attempt at reform, like Gorbachev's in the USSR, would accelerate the regime's collapse rather than prolong it. This formative experience informs his rigid refusal to cede ground on core principles like the mandatory hijab, ensuring a brutal response to dissent.
