The Trump administration has announced a major policy change about the U.S. position on the status of Jerusalem, a decision that may have dramatic repercussions for the delicate peace process between Israelis and Palestinians.

Senior administration officials said Tuesday that President Donald Trump plans to officially recognize Jerusalem as Israels capital and will direct the State Department to begin preparing to relocate the U.S. Embassy in Israel from Tel Aviv to Jerusalem.

Like other presidential candidates before him, Trump repeatedly promised during his campaign to recognize Jerusalem as the capital of Israel and move the U.S. Embassy there. On Tuesday, the president reportedly confirmed his intention to do so in a call with Palestinian President Mahmoud Abbas.

The move will likely placate the Israeli government and conservative allies in the U.S. but may meet with a furious response from Palestinians and complicate the already daunting task of brokering an Israeli-Palestinian peace accord.

Trump did not follow through on his promise during his first months in office, but facing a deadline this week, the president finally decided to move forward with the plan.
