Nuke Iran's oilfields, then they'll have nothing. Food for uranium.
The U.S. should start bombing Iran's nuclear sites immediately and keep bombing them until they have been pounded into oblivion. At the same time, we should bomb their oil pipelines, completely shutting them down. These actions will castrate Iran and force regime change without a single American soldier entering the country.
Instead, it sounds like the new Secretary of Defense favors appeasement, and Bush will coast into retirement without taking decisive action.
