(10.10.2018) The United States marked a melancholy anniversary on Oct. 7 — 17 years to the day that we began offensive military operations in Afghanistan in response to the September 11 terror attacks. Someone born in early October of 2001 is now old enough to fight — and die — in the same war. And although the scope and shape of the conflict has changed in numerous, material ways over these 17 years, it is still being conducted under the same cryptic, 60-word statute Congress enacted one week after the World Trade Center collapsed — the Authorization for the Use of Military Force, or “AUMF.”
