The September 11, 2001 terrorist attacks on the United States would lead to the first Article 5 invocation in NATO history and its longest out of area mission, Afghanistan. October 7 2019 marks the 19th anniversary of Operation Enduring Freedom .The movie 12 Strong (Fuglsig, 2018) captures the first days of Operation Enduring Freedom by telling the story of the first Special Forces team deployed to Afghanistan after 9/11; where the team must work with an Afghan warlord to take down the Taliban. By December 2001 they succeeded in winning the war against the Taliban, but keeping the peace had just started. Following the Bonn Agreement, and on basis of UNSC resolution 1386, NATO took charge of the International Security Assistance Force (ISAF).
After 13 years, on December 28, 2014, President Barack Obama announced the end of Operation Enduring Freedom in Afghanistan, and simultaneously NATO ended the ISAF mission. Continued operations in Afghanistan by the United States' military forces, both non-combat and combat, now occur under the name Operation Freedom's Sentinel, while NATO continued its presence under the new operation Resolute Support Mission (RSM).
