About 10 days after 9/11, I went through the Pentagon, and I saw Secretary Rumsfeld and Deputy Secretary Wolfowitz. I went downstairs just to say hello to some of the people on the Joint Staff who used to work for me, and one of the generals called me in. He said, “Sir, you’ve got to come in and talk to me a second.” I said, “Well, you’re too busy.” He said, “No, no.” He says, “We’ve made the decision we’re going to war with Iraq.” This was on or about the 20th of September.

I said, “We’re going to war with Iraq? Why?” He said, “I don’t know.” He said, “I guess they don’t know what else to do.” So I said, “Well, did they find some information connecting Saddam to al-Qaeda?” He said, “No, no.” He says, “There’s nothing new that way. They just made the decision to go to war with Iraq.” He said, “I guess it’s like we don’t know what to do about terrorists, but we’ve got a good military, and we can take down governments.” And he said, “I guess if the only tool you have is a hammer, every problem has to look like a nail.”

Now listen here: Printing top secret information. I don't care how they feel about the war. Whether they're for or against it. They can't and should not do this and attack the integrity of government and by God, I'm gonna fight that son of a bitching paper. They don't know what's gonna hit them now.

Ridding Iraq of weapons of mass destruction. That was the whole idea, right? That‘s why we went. I am reluctant to let that fact disappear down the memory hole, because if — as the war ends, or at least starts to end — if, at this time, the history of the war is written as us going there to topple the regime of a bad man when that frankly isn‘t why were told that we were going there — Aren‘t we still at risk of making this horrific mistake again? And, aren‘t we letting the people who foisted the WMD idea on us, not many years ago, aren‘t we sort of letting them get away with it?

As I look back at our lock-step march toward war with Iraq, I realize that it didn’t seem to matter to us that we used shoddy or cherry-picked intelligence; that it was unrealistic to argue that the war would “pay for itself,” rather than cost trillions of dollars; that we might be hopelessly naïve in thinking that the war would lead to democracy instead of pushing the region into a downward spiral.
The sole purpose of our actions was to sell the American people on the case for war with Iraq. Polls show that we did. Mr. Trump and his team are trying to do it again. If we’re not careful, they’ll succeed.

I asked about victory and how it might be achieved, and he said that would require more than security in Iraq. There would have to be self-government and the physical reconstruction of the country- all the "lines of operation" in Casey's war plan. "Is this going to happen in your lifetime?" I asked. "Yes, it is. Well, I hope, yeah. I don't know," he said. "I should retract that line. It can happen in my lifetime." "Do you have any doubts this was the right decision to invade Iraq?" "I have no doubts at all," he said. "None. Zero." "Isn't the process, though, you always have to doubt?" I said. "I live on doubt." "I'm sorry for you," the Marine general said. "Don't be sorry for me," I said. "It's a wonderful process." "I do not have doubt about what we've done," he said. "We did not do this. When we were sitting home minding our own business, we got attacked on 9/11."
