The day after the long-overdue termination of the U.S. program supporting Syrian rebels, a hawkish high-ranking Defense Department official (in the words of the headline “Trump’s top Middle East aide”) got the boot:
Harvey was viewed as one of Trump’s more hawkish foreign policy advisers—particularly on Iran, whose leadership he has studied closely and which he recommends confronting more aggressively. He has also been a staunch critic of the Iran nuclear deal. And Harvey has pushed for a strong U.S. military role against the Islamic State in Syria. Many military officials consider him the government’s most knowledgeable source on the Sunni insurgency in Iraq and Syria.
I consider this at least provisional evidence that there remains a degree of anti-intervention sentiment within the Trump Administration.
