Joe Biden on ending longest US war: 'September 11 attacks cannot explain why American forces still there 20 years later'

President Joe Biden says he will withdraw remaining US troops from Afghanistan, declaring that the September 11 attacks “cannot explain” why American forces should still be there 20 years after the deadliest terror assault on the United States.

His plan is to pull out all American forces — numbering 2,500 now — by September 11 this year, the anniversary of the attacks, which were coordinated from Afghanistan.

The US cannot continue to pour resources into an intractable war and expect different results, Mr Biden said.

The drawdown would begin rather than conclude by May 1, which has been the deadline for full withdrawal under a peace agreement the Trump administration reached with the Taliban last year.

“It is time to end America’s longest war,” Mr Biden said, but he added that the US will “not conduct a hasty rush to the exit”.

“We cannot continue the cycle of extending or expanding our military presence in Afghanistan hoping to create the ideal conditions for our withdrawal, expecting a different result,” Mr Biden said.

“I am now the fourth United States president to preside over an American troop presence in Afghanistan. Two Republicans. Two Democrats. I will not pass this responsibility to a fifth.

The decision marks perhaps the most significant foreign policy decision for Mr Biden in the early going of his presidency.

He has long been sceptical about the US presence in Afghanistan. As Barack Obama’s vice president, Mr Biden was a lonely voice in the administration who advised the 44th president to tilt towards a smaller counterterrorism role in the country while military advisers were urging a troop build-up to counter Taliban gains.

Mr Biden has also made clear he wants to recalibrate US foreign policy to face bigger challenges posed by China and Russia.

Withdrawing all US troops comes with clear risks. It could boost the Taliban’s effort to claw back power and undo gains toward democracy and women’s rights made over the past two decades.

It also opens Mr Biden to criticism, mostly Republicans and some Democrats, even though former president Donald Trump had also wanted a full withdrawal.
