It isn’t just the PLO who is going to have to act like a nation now. Israel is going to have to treat the West Bank as a nation. Which it doesn’t want to. Before this the West Bank was an outlaw and Israel was only limited only by outrage in what it could do.

Now both sides are under international law, and I suspect neither side is going to like it very much. To suddenly be limited in what they can do to each other after decades of absolute freedom won’t be a pleasant experience for either of them.
