Actually, I think GAZA is at least 60% responsible for Israel having to build Iron Dome. So Gaza should have to reimburse Israel for the cost.
Israel should never give another schekel to the Pals. Permanently chop off the electricity too. Zero power & zero cement . F them all . Let them spend the rest of their worthless lives living in the rubble . Maybe they’ll get the message and leave . Or commit suicide en masse.
