Anybody remember the first thing the Pallies did when the Jewish settlers were cleared out of Gaza in the last "Land for Peace" fiasco?
The settlers had acres of high tech greenhouses which were being used to grow produce for export cash which they left in nice, operable condition.
If you guessed "smash them up and render them useless" then go to the head of the class.
Actually they did one other thing just as quickly. Just to celebrate they fired some rockets into Israel. Yes, the rockets and grenades started already the first day after Israel left Gaza.
