Let's not have another Iran hostage crisis ...

The Iran hostage crisis, referred to in Persian as تسخیر لانه جاسوسی امریکا (literally "Conquest of the American Spy Den,"), was a diplomatic crisis between Iran and the United States. Fifty-Two American diplomats and citizens were held hostage for 444 days ...

In case you don't remember that mess ... http://en.wikipedia.org/wiki/Iran_hostage_crisis

A couple of hundred security troops are not an army of invasion.

The Russians are helping out supplying the Shia led Iraq government with aircraft and the Iranians helping out supplying some elite Republican Guard troops (commandos?).

Looks like the mess is getting real ...

Getting sucked into this mess would be a mistake. Guarding (securing) our diplomatic interests would not be a mistake. Total evacuation from Iraq, including diplomatic presence, may be a good idea.
