I'm biased. As a Western Liberal I'm going to have a preference for the Western Liberals. I'm not a fan of Israel's "kill a roach with a shot-gun" and their continued expansion of settlements on the West Bank is nothing short of criminal. However I really can't bring myself to sympathize that much with the Palestinian position. In short the various Palestinian authorities have been waging total war on Israel since the 1930s and been getting sonned, yet even as the conflict has gotten more and more lop-sided the Palestinian authorities still insist on waging total war.
Thing is, if you wage war on Israel with specific and limited concessions you can potentially get those concessions, see:

Plus you also have the issue that Israel is still winning. They've secured peace with every one of their Arab neighbors, largely through military victory, and great improved the security of the state of Israel itself...to the point where 3 Israelis being killed in a rocket attack is now a big deal (Israelis being killed in terrorist attacks, raids, and skirmishes used to be a pretty common thing).
