Swapping Bergdahl for illegal enemy combatants (terrorists, in common parlance) signaled unmistakably to Taliban and al Qaeda that Obama is determined to withdraw from Afghanistan no matter what the cost to the United States or those in Afghanistan fighting to remain free.

Just like Sept. 11, only with nuclear weapons this time, that's the threat. I think that is the threat. I think it's just facing reality. It's not a happy reality, but it's reality and if you don't deal with it, it will become even more unpleasant.

I'm obviously aware that people are quite focused on the economy rather than foreign policy issues, but that is something that should and can be altered as people see the nature of the threats around the world that we face.

It was right to overthrow Saddam Hussein. It was the regime itself that was a threat. I think in hindsight, what I would have done is turn authority back over to Iraqis much more quickly and say: "Your country, you figure out how to run it."

I don't think I would have to run a campaign that's financed like General Motors.

I think the International Criminal Court could be a threat to American security interests, because the prosecutor of the court has enormous discretion in going after war crimes. And the way the Statute of Rome is written, responsibility for war crimes can be taken all the way up the chain of command. This is the sort of investigation that some people who live in Fairyland might like to undertake, but which bears no relationship at all to conditions in the real world.

We need a strong and effective State Department. We can't conduct American affairs in the world without it.
