"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."
