Boycotts don't work. They work in certain isolated situations, where you have some potential. But in the main, the best way to bring about freedom in a society is to normalize, have tourism, have trade, have contact.

Life is a horror for the Korean people. And I think isolating them further is going to make life more miserable.

I was able to do something that people cant do these days, which is to have quality time with the guys who were trying to be president and a number of them who got the job.

Eisenhower provided the first break in the Cold War, by bringing Khrushchev to the United States, in humanizing the Soviets; and then Nixon, by making the opening to China; and then Reagan, even meeting in Reykjavik with Gorbachev and acknowledging that nuclear weapons are a horror. So I won't accept that Republicans just escalate. Republicans, at least when they were more moderate, they were maybe even more isolationist, they sometimes brought sanity to the debate. We don't have that now. We have - all these Republicans have gone off the neoconservative deep end.

Eisenhower was a pretty peace-oriented president. Truman was a pretty hawkish. I would argue, if we had more time, I would argue Truman had a lot to do with getting the Cold War going.

Richard Nixon even before becoming president, before meeting Henry Kissinger, he said, "This is ridiculous. Communism is nationalist. The Chinese and Russian and Yugoslav and Cuban and - none of these communists get along, and the Koreans and the Vietnamese, and we can do business with them." And then he opened up to China, and that's when the Cold War started.

Nuclear weapons are inherently threatening to all of civilization. If that had been a nuclear weapon at the World Trade Center, even the most primitive kind of the Hiroshima, Nagasaki, you wouldn't have a Manhattan. There wouldn't be a democracy of any kind in America.
