Deja vu...
While I don't think attacking Iran is a good idea, at least for the U.S., I can't help but noticed the usual anti-war progression.
Step one appears to be a gross inflation of the capabilities of the enemy, with many references to their formidability, and how many other armies have failed to defeat them. Heard it before Afghanistan, heard it before the Gulf War, and heard it before the current war in Iraq, although in the latter case it's been painted over quickly with "we knew all the time that the army would be a pushover."
