The War In Afghanistan Is Officially Over For The United States

In 2012, Obama announced that the U.S. would withdraw its troops from Afghanistan by the end of 2014, and he's made good on his word. After 13 years, the U.S. has formally ended the war in Afghanistan. Though the U.S. and Britain ended operations in Afghanistan in October, the chapter was officially and symbolically closed on Sunday with a ceremony at NATO's military headquarters in Kabul. After marking the official end of the International Security Assistance Force (ISAF), a new international mission was announced that would see NATO in a supporting role.

During the ceremony, General John Campbell, commander of the ISAF, rolled up the green and white ISAF flag and unveiled a new one, representing a new mission and the next chapter for Afghanistan. Campbell announced the NATO-led mission Resolute Support, which would provide training, assistance, and guidance to Afghan security forces, ministries, and institutions but will not involve combat.

Campbell announced at the event that "Resolute Support will serve as the bedrock of an enduring partnership" between NATO and Afghanistan. The mission will launch on January 1, 2015, and will involve around 11,000 remaining U.S. soldiers.

After 13 years, many in Afghanistan have mixed feelings about the withdraw of foreign troops as Taliban insurgents remain a prominent and dangerous threat to this day. In fact, this year has been the most deadly since the war began with civilian casualties expected to reach 10,000 for the first time.

Before Resolute Support kicks off the next — and perhaps last — chapter, take a look back at the major events of the war in Afghanistan.
