Secretary of State Mike Pompeo delivered a speech to the Republican National Convention that aired Tuesday night looking over the Old City of Jerusalem. It was a fitting setting because it was the location of one of President Trump’s boldest foreign policy moves.

In 2017, Trump followed through on a promise that many other presidents had reneged on when he recognized the simple reality that Jerusalem was the capital of Israel. Though this should be obvious, especially given that the city has served as home to the Israeli government, it was a move that prior presidents had resisted because they listened to warnings of so-called experts that it would blow up the Middle East.
