Not really but maybe with a stretch. A peace between Israel and the 'Palestinians' would end the power of Arafat and his murderous thugs. So, Israel moves toward peace - Palestinians attack - must maintain power.
When Bush becomes conciliatory toward the Dems, they grin their feral grin and stay quiet while they grab what they can. When Bush does something that makes him look good, the country, the military, or conservatives, or 'cowboy diplomacy' etc., then they scream like the wicked cross between harpies and banshees they are. (Pelosi was WAY scary after the speech)
If that were the case, then the Palestinians would only maintain the same level of terror in response to concessions by Israel. The reason they actually step up terror in response is that they know their tactics are working, so they do more of what works for them.
Same with the Democrats.
