After 10 months of educating themselves on the complexities of the world’s most intractable dispute, White House officials said, Mr. Trump’s team of relative newcomers to Middle East peacemaking has moved into a new phase of its venture in hopes of transforming what it has learned into tangible steps to end a stalemate that has frustrated even presidents with more experience in the region…

Mr. Trump’s team has collected “non-papers” exploring various issues related to the Israeli-Palestinian conflict, and officials said they expected to address such perennial dividing points as the status of Jerusalem and settlements in the occupied West Bank. Although Mr. Trump has not committed to a Palestinian state, analysts said they anticipated that the plan will have to be built around the so-called two-state solution that has been the core of peacemaking efforts for years.
