“It is not weakness but wisdom to talk not just to our friends but to our enemies, like Roosevelt did and Kennedy did and Truman did,” he just said. Let’s see now. Roosevelt went to war with Japan and Germany; he did not “talk” to them. Truman dropped two atomic bombs on Japan. Kennedy did do some negotiating, so he’s got something there, but he also led the United States to the brink of war over Cuba. The more apposite examples, here, would be Richard Nixon (SALT treaty), Ronald Reagan (Reykjavik summit) and Jimmy Carter. Nixon and Reagan were Republicans, and Carter is currently looking for any terrorist whose boot he can lick. Maybe this is a line Obama should drop from his stump speech.
