We'd be better off if the whole purpose of the adventure in Iraq was, say, to protect Israel or to protect the flow of oil to America and keep it at a reasonable price and try to get some more control. If it was about oil, going into Iraq, I guess, could have made sense. But at a certain point, when the insurgency began and we were in real trouble, there would have been some awareness that we were going to jeopardize the oil.

I have a theory in life that there is no learning. There is no learning curve. Everything is tabula rasa. Everybody has to discover things for themselves.

When George W.Bush attacked Afghanistan, it was widely hailed, and the failure of our war there wasn't understood. Within a few months of attacking Afghanistan, Bush clearly moved on to get ready for Iraq, long before Osama bin Laden or Al Qaeda were dispensed with. There was never any serious debate in the press about whether even the notion that every Taliban was our enemy was valid. A lot of assumptions about that war were never challenged.

I don't know Condoleezza Rice personally. I'm sure she's a nice lady, and I'm sure she plays the piano well. But she was a very bad National Security Adviser. The National Security Adviser is supposed to be an arbiter of policy and open minded in internal debates.

I don't know whether God talks to him or whether he's trying to undo what his father did. But he believes in the mission. The body bags aren't going to deter him. Public dissent isn't going to deter him. He's going to go ahead. And that's more frightening.

In Vietnam, our soldiers came back and they were reviled as baby killers, in shame and humiliation. It isn't happening now, but I will tell you, there has never been an American army as violent and murderous as our army has been in Iraq.

I'm worried about people who say Bush is lying. It's much more frightening that he's not lying, that he believes what he believes: that it's his mission to change the Middle East into a democracy. That's more unnerving.
