Your comments are well thought out, but Newt’s comment was inappropriate only IF he was interested in being an objective intermediater between the Israelis and the Palistinians. But it looks like Newt thinks there’s no chance for “peace” talks until the Palistinians stop launching missiles, and teaching their kids that murdering Jews is heroic. And there’s additionally no chance if the Palistinians continue to think that Israel is their historic homeland.
How many countries surround Israel? How many of those countries accept Israel's existence? Jordan, may be. Hezbollah in Lebanon? The new Egypt? What exactly is there to negotiate even if you are a professional intermediator?
If that is his true intent, then far better to keep your opinion to yourself until you become President.
