Iran, anybody?

Well, things are heating up a bit. According to al-Ahram, the US has moved 2 aircraft carriers closer to Iran (I'm not sure if this is the 1-2 I had previously heard about or if these are new ones - I'll try to find out). And we're moving Patriot missile systems (for defense) to most of the Gulf States. Also, 2 US generals and an admiral published a letter in the Times about why we shouldn't attack Iran.
