Evening Edition: The War In Afghanistan And Emerging National Security Threats

This Veterans Day could be a little more poignant for those who served in Afghanistan or lost family members or friends to the 20-year war. How the war ended and the questions about what we actually accomplished there remain open for debate. FOX’S Trey Yingst speaks to retired U.S. Army Lt. General H.R. McMaster, also former National Security Advisor and author of ‘Battlegrounds: The Fight To Defend The Free World’, about his thoughts on the war in Afghanistan and what are the emerging national security threats the U.S. faces.
