(CNN) President Donald Trump once famously said he knew more about ISIS than US generals do. Republican Sen. Lindsey Graham, usually a Trump ally, blasted the decision on the Senate floor Wednesday night. "We have defeated ISIS in Syria, my only reason for being there during the Trump Presidency," Trump wrote on Twitter. Unlike many of the President's most significant, shocking decisions, the Syria withdrawal order did not test constitutional norms and was well within the guardrails of mainstream political thought on overseas deployments. The Syria pullout order came after a call last Friday between Trump and Turkish President Recep Tayyip Erdogan.
