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

I have looked at public opinion polls in France in the late 1940s and early 1950s during the height of Marshall Plan aid. They had a very negative attitude towards the United States then. There were negative attitudes towards the United States because of Vietnam. There were negative attitudes about the United States when Reagan wanted to deploy intermediate range ballistic missiles. I don't think the president should base his foreign policy on American public opinion polls, let alone foreign public opinion polls.

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.

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

The Nobel Peace Prize has become hopelessly politicized. I think it cheapens the prize itself.

There's no such thing as the United Nations. If the U.N. secretary building in New York lost 10 stories, it wouldn't make a bit of difference.
