Well no one disputes that it's a big problem. The question remains though, in what cynical world is it uniquely Israel's problem to solve? Where is the damn UN on day two after Pal independence?
The problems of the region are after all, regional. A water balloon. Squish it in one place and it bulges out somewhere else. There is no way that tiny Israel can fix it. And this is the plan of the ring arab states. Do nothing, let it all descend into flaming starving anarchy and then do nothing some more until Israel is forced to become involved. This is merely another form of warfare.
