The newspaper reported on Tuesday, citing Sullivan's aides, that Biden insisted he stay in his position.
The withdrawal from Afghanistan broke the "primary cohesion" of the Biden administration's national security team and created a rift between Sullivan and Secretary of State Antony Blinken.
The withdrawal of American forces from Afghanistan in August 2021 claimed the lives of at least 13 American soldiers and led to the collapse of the Afghan government.
“You can’t end a war like Afghanistan where you’ve built dependencies without it being complicated and challenging,” the US national security adviser told the newspaper. “The choice was: go or stay forever, and it wasn’t an easy choice.”
Sullivan added that the withdrawal of US forces from Afghanistan allowed the United States “to deal with Russia’s invasion of Ukraine in a way that probably wouldn’t have been possible if we had stayed”.
‘Pentagon's Resistance To Biden’
According to the Washington Post, the Pentagon resisted Biden's call to withdraw all American troops from Afghanistan and demanded that "a force of 2,500 remain in Kabul”.
The Washington Post author, citing two close advisers in the US government, wrote that Sullivan initially shared the Pentagon's concerns. However, he decided to "loyally" support Biden's plan for a full withdrawal.
