Diplomacy is not an end in itself if it does not advance U.S. interests.

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.

The North Koreans will sell anything to anybody for hard currency. If Al Queda came up with enough dollars to buy a nuclear weapon from North Korea I don't have any doubt that the North Koreans would sell it to them.

I think some of this fascination with the 'Arab Spring' is just a grand experiment with Israel's survival.

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.

I think it's critical that we return national security issues to the center of the overall political debate in America.
