I was against the disengagement when it happened, but now that it happened Israel needs to fully disengage, and in fact should have done this from day 1.
Israel needs to tell the world, we are leaving Gaza, closing the border, cutting off electricity, water etc. You want to turn the clock back to June 4, 1967, fine, we have NO responsibilities to Gaza.
Let the Palestinians in Gaza figure out how they will get electricity etc. Let them get everything from Egypt,by sea, however they want. Let's see how their fellow Arabs the Egyptians would treat the Palestinians in a situation like that.
Believe it or not Aluf Benn from Haaretz wrote a column today suggesting exactly this.
