Would we be so willing to accept a wall built around crime ridden American ghettos because crime and drugs spill out of those places into the surrounding areas? No, of course not. That would be discriminating against all blacks/hispanics/insert other minority who live in that area. Yes, terrorism is a problem that must be remedied, but targeting all Palestinians just feeds the problem. It gives the radical leaders more propaganda to feed to the impressionable youth that are wondering why they have to cross a wall to go to school.
