Driving the news: The White House gave Israeli Prime Minister Benjamin Netanyahu a green light to immediately annex about 30% of the West Bank, a step every previous U.S. administration vehemently opposed. Netanyahu plans to act on that opportunity as soon as Sunday.

Our thought bubble: If Israel does annex the Jordan Valley, it will entrench Israel’s control and fundamentally change the equation for any future negotiations.

Green-lighting annexations is an even more dramatic step from Trump than moving the U.S. embassy to Jerusalem or recognizing Israeli sovereignty over the Golan Heights.

It could also ultimately be the least reversible of those steps. Once annexation happens, it’s hard to reverse.
