DOHA, Qatar (AP) The United States signed a peace agreement with Taliban militants on Saturday aimed at bringing an end to 18 years of bloodshed in Afghanistan that began after 9/11 and allowing U.S. troops to return home from Americas longest war.

This historic deal, signed by chief negotiators from the two sides and witnessed by Secretary of State Mike Pompeo in the Qatari capital of Doha, could see the withdrawal of all American and allied forces in the next 14 months and allow President Donald Trump to fulfill a key campaign pledge to extract the U.S. from endless wars. It sets the stage for intra-Afghan peace talks to begin by March 10 during which a permanent ceasefire will be negotiated and the Taliban agree to meet with all factions.

Under the agreement, the U.S. would draw its forces down to 8,600 from 13,000 in the next 3-4 months, with the remaining U.S. forces withdrawing in 14 months. The complete pullout would depend on the Taliban meeting their commitments to prevent terrorism, including specific obligations to renounce al-Qaida and prevent that group and others from using Afghan soil to plot attacks on the U.S. or its allies. The deal does not, however, tie the U.S. withdrawal to any specific outcome from the all Afghan talks, according to U.S. officials.

We will closely watch the Talibans compliance with their commitments, and calibrate the pace of our withdrawal to their actions. This is how we will ensure that Afghanistan never again serves as a base for international terrorists, said Pompeo. He acknowledged that the road ahead would be difficult but said the deal represented the best opportunity for peace in a generation.
