Starting a war with Iran would be catastrophically stupid. For that reason, it seems all but inevitable. BushCo seems hellbent on a political house-wrecking party; he knows he isn't getting his security deposit back so he's invited his buddies over for a two-year kegger.Until BushCo spread it's unique form of freedom on Iraq, Saddam's secular, Sunni-dominated regime served as a useful check on Iran's theocratic Shiite power. Now, a ruined Iraq provides a fertile breeding ground for Iranian opportunists and lets the Iranians concentrate on their real enemy, Israel.
Iran poses no direct military threat to Americans at home, but Israel is not so lucky. Iran makes Israel nervous, and for good reason. The recent conflict in Lebanon proved that Hezbollah, with Iranian backing, is capable of acting as an effective and highly organized military organization.
As the Shiites rush to fill the power vacuum left by the removal of Saddam's Sunni regime, our Sunni allies in Saudi Arabia are getting alarmed...if Tehran gets the 'bomb', Riyadh is gonna want it too...the thing is, BushCo has to find a way to kiss Israel's ass while simultaneously pleasuring the Saudis, which is tricky business because Israel and Arabia hate each other.
BushCo is not at all adept at nuance or diplomancy, but they do understand that every time a U.S. soldier fires a shot, the war machine gets to sell another bullet. Munitions are profitable and life is cheap, so the simplest, stupidest, most tragic and amoral response would be to start WW3 by attacking Iran.
Given our current leadership, it seems inevitable.
