Trump announced that the U.S. will move its embassy from Tel Aviv to Jerusalem, a decision that breaks with decades of Washington policy.
Saudi Arabia has called the move a "flagrant provocation," while Turkish President Recep Erdogan described Jerusalem's current status as a "red line for Muslims."
Recognizing Jerusalem as the capital of Israel was a Trump pledge during his electoral campaign. In defense of the move, his administration said: "We view this as a recognition of reality."
Some see Trump's stance as a pandering to his domestic conservative base, but why is recognizing Jerusalem, and not Tel Aviv, as the Israeli capital viewed as potentially dangerous?
