I think we give Jimmy Carter too much credit to think he knew what was going to happen when he used the word "apartheid." It's provocative, but it was like a nuclear bomb in Israel. And yet that word is used all the time in the Israeli press. There's a double standard there. He probably picked it up in Israel, as it's commonly discussed. I'd be a little surprised if he understood how it was going to be used against him. He doesn't have a highly developed emotional detector. As a politician, that was a weakness.
