The United States strongly supports Israel in its war against Hamas, but is increasingly at odds with its Middle East ally over what will happen to the Gaza Strip once the war winds down.

Israel’s prime minister, Benjamin Netanyahu, this week announced that Israel would retain an open-ended security presence in Gaza. Israeli officials talk of imposing a buffer zone to keep Palestinians away from the Israeli border. They rule out any role for the Palestinian Authority, which was ousted from Gaza by Hamas in 2007 but governs semi-autonomous areas of the occupied West Bank.

The United States has laid out a much different vision. Top officials have said they will not allow Israel to reoccupy Gaza or further shrink its already small territory. They have repeatedly called for a return of the internationally recognized Palestinian Authority and the resumption of peace talks aimed at establishing a Palestinian state alongside Israel.

These conflicting visions have set the stage for difficult discussions between Israel and the U.S.
