Israel supplies electricity and water to the Gaza Strip. Moreover, some Gaza laborers still do work in Israel. If the inhabitants are reasonable, they will realize that a Hamas terror state will work against their own best interests. But if they are not - and it appears that too many are not - then Gaza\s "highest population density in the world, terrible poverty, a huge collection of arms and a radical leadership that plans to continue an armed struggle" may yet lead to a situation where Israel will cut off all power and water to the Strip and sever all economic ties - something that could lead to a disaster, with people dying in the streets.
