I don't think we went to war [in Iraq] because of oil, but the only thing I can fit together with Cheney and his gang is that they're smarter than they're acting. They went to war in the hope they would be able to do two things. One, have a government that sat on a whole bunch of oil that still exists in the world that would be indebted to us. Two, have permanent military bases in Iraq to dominate that part of the world to be able to control oil. Not to steal it for American oil companies, but to be able to control the pricing, control the access of it, a very Machiavellian view. There's nothing idealistic about Cheney.
I don't know what President Bush thinks, but I think he's bought hook, line and sinker the Cheney rationale that the only way for us to be able to be dominant in the 21st century is to use our overwhelming power in the face of the moral disapprobation of the rest of the world, threaten the rest of the world, and that's how we avoid war in the future...
[As for Iran] the president has no constitutional authority to take this nation to war against a country of 70 million people, unless we're attacked or unless there is proof that we are about to be attacked. And if he does, I would move to impeach him... I don't say it lightly. I say it because they should understand that what they were threatening, what they were saying... what we were about to do would be the most disastrous thing that could be done at this moment in our history.
