The fact that the Trump administration’s decision to move the U.S. embassy in Israel from Tel Aviv to Jerusalem breaks with 60 years of U.S. policy; has caused the U.S. to put troops on alert and warn Americans traveling abroad, and is opposed by our allies worldwide; tells you everything you need to know. It will remove the U.S. as a trusted middleman and weaken our influence in the region.
As explained in a recent Brookings Institute report (and other clippings below):
It is almost impossible to see the logic of the Trump administration’s expected recognition of Jerusalem as Israel’s capital, and possibly moving the U.S. embassy to Israel there—before it even unveils what’s certain to be a controversial plan for Middle East peace, which will be tough enough to sell. . . .
In the meantime, the administration’s assumptions about the limited costs of the move are based on little more than a leap of faith. In fact, the move would go against the very priorities that the administration has set for itself in the Middle East: fighting Islamist militancy and confronting Iranian influence. Jerusalem is the perfect issue for Iran and Islamist militants to use to mobilize support against the United States and those who endorse its policies.
