The Israeli government displayed its contempt for Kerry's "peace negotiations" by backing a plan to annex a large fraction of the West Bank in order to keep it permanently under siege.

Netanyahu does not care how this affects the "negotiations", since he has no intention of making a peace agreement. I think his goal is to show that he still has the US government cowed; that he can ridicule the US and the "negotiations" and Kerry won't dare make a peep.
