Afghanistan is the longest-running war in American history. The American Civil War, Spanish-American War, World War I, and World War II, combined, all lasted about 17 years and a bit, while the US war in Afghanistan — alone— has endured 18 years.
After 9/11 — which massacred around 3,000 people — the US launched an operation in Afghanistan. Now, after 18 years, the Afghan war needs a new effective US strategy to come to an end — at least 139,000 Afghans and roughly 2,400 US service members have died in this war, and yet, the insurgents today are better equipped and control more areas than ever before.
