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.

Sorry, but which war are you referring to?

jere is suggesting that it led to Iraq declaring war on Iran, as mentioned here:
