I just saw Daniel Pipes speak. There are two points of great moral depth underlying his message that I've never noticed before:
1. Evil simply cannot be tolerated; it must be faced and relentlessly opposed.
The Palestinian attitude toward Israel is evil. It should be opposed with all force necessary and with no negotiations. You don't negotiate with someone trying to kill you. You use brute force to shut him down.
2. People are free to decide how to act.
The Palestinians can simply accept the existence of Israel and stop killing Israelis. They can build their own society. It's up to them to do.
These are fundamental truths. They are regularly denied by many analysts of the Palestinian-Israeli conflict.
