Actually, IMO, Iran has forced what would have been a sketchy conventional war for the Coalition of the Willing to win quickly (for numerous reasons) into a certain War of Iran's Total Obliteration by leaving no option but rapid escalation.
Iran is gambling on the pressure of the World Communists inside and outside of America to cause America to back down from doing what Bush unequivocally said: "Iran will not be allowed to have nukes".
I believed President Bush then re: NO NUCLEAR IRAN! and I have no reason to doubt him now.
And dont you know that N Korea is watching every move the rest of the world makes....if we deal w/ Iran effectively we might eliminate N Korea as a threat.
