President Donald Trump has decided not to immediately move the U.S. embassy in Israel to Jerusalem, a senior White House official said, violating a campaign promise but avoiding a provocation that could drive Palestinians away from peace talks.

The official said the administration considers its discussions with both the Israeli government and the Palestinian Authority to be promising, with the Palestinians in particular agreeing to talk without preconditions. The official asked not to be identified because of the sensitivity of the matter.

Trump said in a speech to the American Israeli Political Action Committee conference in March 2016 that he would move the U.S. embassy to Jerusalem, calling it “the eternal capital of the Jewish people.” The city is claimed as a capital by both Jews and Palestinians, however, and relocating the U.S. embassy — essentially declaring Jerusalem to be Israeli territory — would raise tensions.
