I would think the overriding issue for Israelis is to stop the killing of Jews. Period. Whatever that takes.
Except for a relatively small number of zealots, religious nationalists with a messiah complex and their American supporters, most Israelis, and indeed most Jews everywhere, see it the way you do. I don't feel that holding onto lands with a million and a half hostile Arabs and a few thousand Jews stuck in there in Gaza made any sense at all.
There is nothing more important in Judaism than saving lives. There are no holy sites in Gaza and precious little Jewish history at all. There is lots of the "promised land" we don't control. I suppose some would want us to invade Jordan, Syria, and Lebanon to claim it. I prefer to believe that promise will be fulfilled when moshiach comes, not before.
So... I continue to support unilateral separation and I plan to vote for Kadima. I continue to be criticized and called a leftist on Free Republic even though I am center-right in Israel. If you don't agree with Benny Elon (or perhaps consider him too liberal) on Free Republic then you will be attacked and called insane. Get used to it.
