Water, too, IIRC.
I've been saying this for years. Plus, they should bulldoze an ever-widening no-man's zone, increasing it's depth for every terrorist outbreak.
Then why has Netanyahu not done this? After a few days the entire population—all 2,500,000 of them —will rebel against Hamas and be up in arms against them. The usual suspects will condemn Israel, but all Netanyahu has to say is: stop the missiles, stop your hatred toward Israel, and the water and electricity we provide for free will come back on. So simple yet why has it not been done?????
