And yet, even all this misery is overshadowed by a grimmer fact: no water. Gaza's public water supply is pumped by electricity. The taps, too, are dry. No sewage system. And again, word is that the electricity is out for at least six months.
The Gaza aquifer is already contaminated with sea water and sewage, due to over-pumping (partly by those now-abandoned Israeli settlements) and the grossly inadequate sewage system. To be drinkable, well water is purified through machinery run by electricity. Otherwise, the brackish water must at least be boiled before it can be consumed, but this requires electricity or gas. And people will soon have neither.
Drinking unpurified water means sickness, even cholera. If cholera breaks out, it will spread like wildfire in a population so densely packed and lacking fuel or water for sanitation. And the hospitals and clinics aren't functioning, either, because there is no electricity.
Finally, people can't leave. None of the neighboring countries have resources to absorb a million desperate and impoverished refugees: logistically and politically, the flood would entirely destabilize Egypt, for example. But Palestinians in Gaza can't seek sanctuary with their relatives in the West Bank, either, because they can't get out of Gaza to get there. They can't even go over the border into Egypt and around through Jordan, because Israel will no longer allow people with Gaza identification cards to enter the West Bank. In any case, a cordon of Palestinian police are blocking people from trying to scramble over the Egyptian border--and war refugees have tried, through a hole blown open by militants, clutching packages and children.
