Speaking at an emergency session of the parliament, British lawmakers also vented their anger at Prime Minister Boris Johnson and U.S. President Joe Biden over the collapse of Afghanistan into Taliban hands, calling it a failure of intelligence, leadership and moral duty.
Johnson said the Taliban would be judged on their actions, not their words, after they sought to convince the world they would not seek revenge.
But, barely a minute into his opening address, Johnson faced a critical interruption from a member of his own Conservative Party, setting the tone for what would be a skeptically-received speech about how Britain wanted to be at the heart of an international coalition holding the Taliban to account.
Several lawmakers on Wednesday focused on the U.S. decision to withdraw - a move which Johnson admitted left Britain with no choice but to pull out its own forces - and Biden's subsequent criticism of Afghan forces' surrender.
"And the final question about whether the UK can lead or participate in a coalition without the U.S. - where is our foreign policy determined? Here or in Washington?" Tobias Ellwood, the chairman of the defence committee said.
Sir Iain Duncan Smith, another Conservative lawmaker pointed out the chaotic scenes at Kabul airport.
"This is a shame on all of us, not just America but also the whole of NATO and here for us in this House," he said.
