The guy who's holding the gun can pull the trigger

McJoan at DailyKos seems to think that Congress can prevent Bush from attacking Iran by not adopting a new resolution permitting him to do so:

There can be little doubt that the fevered dream of Bush and Cheney is extending their debacle into Iran. The likelihood of the Congress passing a separate resolution allowing them to attack Iran (given public opinion, a media that is finally finding its teeth, and Nancy Pelosi and Harry Reid in the Congressional leadership) is exceedingly slim. The only way that Bush can attack Iran at this point would be through the existing Authorization to Use Military Force in Iraq. Is the deeply flawed AUMF broad enough to give Bush that cover? In a conference call a few weeks ago, Harry Reid said, unequivocally, "no."

Sorry. There is no question that Bush/Cheney believe they have the authority to invade Iran without Congressional approval under the President's "Commander in chief" powers , and they are eager to exercise it. The military would be hard put to resist an order to attack if it came from the President. And, it's probably going to come.

That's not to say Bush/Cheney are correct about the president's powers, but the fact is there is no one who can stop them from exercising the powers they think they have. About the best we can do is impeach them afterwards.

It's very hard to stop the guy who's holding the gun from pulling the trigger if he wants to do it.
