WASHINGTON (AP) President Joe Biden s administration on Thursday laid the blame on his predecessor, President Donald Trump , for the deadly and chaotic 2021 withdrawal of U.S. troops from Afghanistan that brought about some of the darkest moments of Bidens presidency.

The White House publicly released a 12-page summary of the results of the so-called hotwash of U.S. policies around the ending of the nations longest war, taking little responsibility for its own actions and asserting that Biden was severely constrained by Trumps decisions.

It does acknowledge that the evacuation of Americans and allies from Afghanistan should have started sooner, but blames the delays on the Afghan government and military, and on U.S. military and intelligence community assessments.

The brief document was drafted by the National Security Council, rather than by an independent entity, with input from Biden himself. The administration said detailed reviews conducted by the State Department and the Pentagon, which the White House said would be transmitted privately to Congress on Thursday, were highly classified and would not be released publicly.

President Bidens choices for how to execute a withdrawal from Afghanistan were severely constrained by conditions created by his predecessor, the White House summary states, noting that when Biden entered office, the Taliban were in the strongest military position that they had been in since 2001, controlling or contesting nearly half of the country.
