I'll admit Israel's past actions have been, shall we say, somewhat suspect. Okay, more than somewhat. The political system is at least partially the captive of the loony religious nuts, so it does little to stop the illegal seizure of Palestinian property. (and in some cases some of the hardcore settlers have been implicated in the disappearances of those who complained)
The number of illegal actions against the Palestinians is staggering, their discrimination against them equally so.
On the other paw, they have been bombed, shot at, and been the subject of missile attacks by these same people and their allies, so there is some reason for their actions. If it were not for the Israeli loony right, I think there would actually be a chance of peace - if the Palestinian loonies would shut up and try as well. They had their best chance shot down by their *own* refusal to enter into meaningful dialogue with an Israeli PM who could have actually accomplished it.
