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.
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 believe that decisions about the timing and manner of death belong to the individual as a human right. I believe it is wrong to withhold medical methods of terminating life painlessly and swiftly when an individual has a rational and clear-minded sustained wish to end his or her life.
... but the important thing is that when you do find one where you really do know what you are doing, you must buy in quantity.... Charlie and I have made a dozen or so very big decisions relative to net worth, although not as big as they should have been. And in each of those, we've known that we were almost certain to be right going in.
One of the very difficult parts of the decision I made on the financial crisis was to use hardworking people's money to help prevent there to be a crisis.
