NATO chief says allies will leave Afghanistan together
Trump, trailing in polls ahead of the November 3 presidential election, made his surprise announcement on Twitter on Wednesday, dramatically speeding up the timeline for ending America's longest war.
"We decided to go into Afghanistan together, we will make decisions on future adjustments together, and when the time is right, we will leave together," Stoltenberg said at a news conference after talks with North Macedonian Prime Minister Zoran Zaev.
It ended its combat operations in Afghanistan in 2014 and has vastly reduced its presence on the ground, but maintains a 12,000-strong force training and advising local forces.
"We will make decisions based on the conditions on the ground, because we think it is extremely important to continue to be committed to the future of Afghanistan, because it is in our interest to preserve the long term security of Afghanistan," he said.
It is not clear whether NATO had any advance warning of Trump's announcement, though Stoltenberg's statement that allies would now "consult on the future of the mission" appeared to indicate that it did not.
After intense US cajoling, the Afghan government and the Taliban last month opened peace talks in Doha, but negotiations have got off to a slow start.
Trump's timeline for withdrawing forces appeared to contradict his own national security advisor Robert O'Brien, who reportedly told an event that the US would cut troops to 2,500 by early 2021.
