Syria is crawling with Iranian revolutionary guard either kill them or get out like Trump ordered but was disobeyed
Trump was not disobeyed. The DoD, along with some Hawks like Lindsey Graham and allies Israel and Jordan, convinced him to stay in the locations they now defend.
Trump withdrew our troops from Northern Syria, which allowed Turkey to invade and push the Kurds we had been supporting about 20 miles south. This is now the Turkish occupied "safe zone" along their southern border.
