This may not answer your question, but it's somewhat related as it kind of did lead to war against Iran (at least that's what wikipedia tells me).

>The Iran hostage crisis was a diplomatic crisis between Iran and the United States where 52 Americans were held hostage for 444 days from November 4, 1979, to January 20, 1981, after a group of Islamist students and militants took over the American Embassy in Tehran in support of the Iranian Revolution.
