Republican Senate Majority Leader Mitch McConnell on Friday blasted President Donald Trump's decision to withdraw U.S. troops from northern Syria, calling the move "a grave strategic mistake" in an op-ed for The Washington Post.

"The recently announced pullout risks repeating the Obama administration's reckless withdrawal from Iraq, which facilitated the rise of the Islamic State in the first place," McConnell wrote in the op-ed.

While his piece does not explicitly lay blame at Trump's feet — or even mention his name — it warns that the Trump administration's sudden foreign policy shift "will leave the American people and homeland less safe, embolden our enemies, and weaken important alliances."

The White House had announced earlier in October — following a call between Trump and Turkish President Recep Tayyip Erdogan — that Turkey would be moving forward with its long-planned incursion into northern Syria, where U.S.-backed Kurdish forces had been fighting ISIS.
