I have made a lot of tactical decisions that historians will look back and say: He shouldn't have done that. He shouldn't have made that decision. And I'll take responsibility for them. I'm human.
I want to make sure that as president of the United States that I'm not asserting in some way that my decisions overrule the decisions of prosecutors who are there to uphold the law.
you must be careful never to allow doubt to paralyze you. always take the decisions you need to take, even if you're not sure you're doing the right thing. You'll never go wrong if, when you make a decision, you keep in mind an old German proverb: 'The devil is in the detail.' Remember that proverb and you'll always be able to turn a wrong decision into a right one.
I wanted to come to Washington, D.C. and help be a transformative President. And I think history, when they look back, will say this is a fellow who knew how to make decisions, and made some tough ones, stood by them, wasn't driven by the latest opinion poll, but was driven by some core principles from which he would not deviate.
I said, going into Iraq, "We've got to take threats seriously before they full materialize." I saw a threat. I fully believe it was the right decision to remove Saddam Hussein, and I fully believe the world is better off without him.
