‘We Are Going to War’: H.R. McMaster Remembers 9/11

Lieutenant General H.R. McMaster was on the phone with the Pentagon when the plane struck the building on September 11, 2001. “I thought, Okay, we are going to war,” he recalls. Twenty-five years after 9/11, McMaster joins Aaron MacLean to discuss the wars that followed. Drawing on his experience as a wartime commander and national security adviser, McMaster explains why he considers Afghanistan a self-defeat, how American withdrawal helped enable the rise of ISIS in Iraq, and why he thinks the latest Iran ceasefire was “a big mistake.”
