"U.S. POSITION ON EAST JERUSALEM:

Official U.S. policy does not recognize Israel’s annexation of East Jerusalem. The official U.S. position is embodied in the U.S. Letter of Assurances to the Palestinians of October 1991, part of the official record of the Madrid Peace Conference. In part, it reads:

[W]e do not recognize Israel’s annexation of East Jerusalem or the extension of its municipal boundaries, and we encourage all sides to avoid unilateral acts that would exacerbate local tensions or make negotiations more difficult or preempt their final outcome."
