Trump's foreign policy: The conservatives' report card

Conservatives must also wonder what happened to the “conservative” foreign policy they were promised in the campaign. The administration certified this month that Iran was complying with the 2015 nuclear deal; according to the Institute for Science and International Security, it isn’t fully. We were supposed to support our allies in Syria fighting both the Islamic State and Assad; we ditched them. We were supposed to get serious about the threat from Russia. In Hamburg this month, Trump again showed how eager he was to oblige his man-crush in the Kremlin, this time at the expense of Israel.

But the deeper flaw of Trump’s foreign policy isn’t psychological. It’s philosophical. The Trump administration is the first to make an open break with the anti-isolationist postwar consensus of Harry Truman, Arthur Vandenberg and Dean Acheson.
