I don't know what the Israeli plan is. I don't think they want to occupy Gaza.Have you noticed no nations are coming to help Hamas? No sanctions, no unified call to arms? Just generic calls for peace.
Israel is going in. They are going to either eradicate Hamas, or set them so far back the power will be broken. There is a very real possibility that the Palestinians will be pushed into Egypt. Or relocated to the West Bank. Or other combinations.
After that, as I said, the Gaza Strip will be leveled, rebuilt as a region of Israel. Free.
I'm guessing that they're just going to wreck it to fuck, run up a massive HAMAS casualty count and then come back out.
