Yes, the Iraq war was a mistake. However, that is a hypothetical question that cannot be answered one way or another.
The
1979 Revolution, which ousted the pro-American Shah and replaced him with the anti-American Supreme Leader
Ayatollah Ruhollah Khomeini,
surprised the United States government, its State Department and intelligence services, which "consistently underestimated the magnitude and long-term implications of this unrest". Six months before the revolution culminated, the
CIA had produced a report, stating that "Iran is not in a revolutionary or even a 'prerevolutionary' situation." On November 4, 1979, the revolutionary group
Muslim Student Followers of the Imam's Line,
angered that the recently deposed Shah had been allowed into the United States, occupied the American embassy in Tehran and took American diplomats hostage. The 52 American diplomats were held hostage for 444 days. In Iran, the incident was seen by many as a blow against American influence in Iran and the liberal-moderate interim government of Prime Minister
Mehdi Bazargan, who opposed the hostage taking and resigned soon after.
Some Iranians were concerned that the United States may have been plotting another coup against their country in 1979 from the American embassy. In the United States, the hostage-taking was seen as a violation of a centuries-old principle of international law that granted
diplomats immunity from arrest and diplomatic compounds
sovereignty in the territory of the host country they occupy. Considered a pivotal episode in the history of
Iran–United States relations, political analysts cite the crisis as having weighed heavily on Jimmy Carter's presidency and run for reelection in the
1980 presidential election. In Iran,
the crisis strengthened the prestige of the Ayatollah Ruhollah Khomeini and the political power of those who supported theocracy and opposed any normalization of relations with the West. The crisis also marked the beginning of U.S. legal action resulting in economic
sanctions against Iran, further weakening ties between Iran and the United States.
Yes, many people in Iran are secularized and I agree with you on that point. However, their leadership and their "hard liners" are insane. Honestly, that is the real problem here.
