US politicians agree on pulling troops out of Afghanistan – but how can they do it and at what...

It’s been a week since Donald Trump suddenly cancelled secret talks with the Taliban, after the Afghan group took responsibility for a deadly car bombing in Kabul.

Mr Trump’s unprecedented negotiations with the Taliban were aimed at ending America’s longest war and bringing US troops home. It’s something the American people have been expecting for a while and both Mr Trump and his predecessor, Barack Obama, have promised to get done, without success. But disagreements remain on how a withdrawal should happen.

The number of US troops in Afghanistan today – around 14,000 – is higher than when Mr Trump entered the White House in 2017. The peace deal with the Taliban was expected to see 5,500 troops withdrawn within five months.
