Ok, let me try to put this in a more actionable way.

There's plenty of horror to go around here. Both parties have committed atrocious crimes, and they plan on continuing to do so indefinitely. (Israel pays lip service to a two-state solutions, while the policy on Arab leaders everywhere is "destroy Israel". But eh, words.)

By (financially!) punishing only one side in this mess, you're rewarding the other side. Are you that certain this is the righteous path?
