I would simply like to go on record as saying that it's a really bad idea for the US to get our military involved with Iran, especially when we have troops stationed on either side of Iran in both Iraq and Afghanistan.
That's a fairly broad swath of land for us to try to control, with about 8 or ten separate ethnicities and at least three governments to co-opt, just in those three countries.
Remember folks, you heard it here first.

(And, you know, the governments of Jordan, Syria, Pakistan, Tajikistan, Kyrgyzstan, Uzbekistan, Kazakhstan, Uzbekistan, and Turkmenistan aren't the most stable things either. Take a good look at that map and figure out how YOU would get all of potentates and non-democratic nations in Central Asia to behave themselves.)
