If I were in charge, my solution would be: put them all into the Gaza strip, extend it if necessary and build quarters for those from the West Bank. Then build a real wall, like the Berlin wall and install missile defense (against the Kazzams) and everything. Problem solved. IMO there will not be real reconciliation in the forseeable future, so those two people have to be separated. The Berlin wall was a bad thing because it forced people to stay inside the eastern block. The israeli wall will only keep palestinians out of Israel so its a totally different thing, palestinians could still go anywhere they want via Egypt or the Mediterranean.
