It looks like negotiations have broken down. Barak is not looking for any reasonable solutions within the letter of the law. Ahead of elections, he wants to prove to his dwindling constituency that he is tough on somebody, and since he isn't tough on the actual enemy, it might as well be the settlers.

Maybe he is trying to get rid of his Barak Barach nickname ("Barak ran away", which he has done on a number of occasions).

From here it looks like he will try to expel the residents on Shabbat when they won't be able to call for local reinforcement from the surrounding communities.

I only wonder how many settlers has he ordered to be shot during the expulsion - and I'm serious with that question.
