The United States’ withdrawal from Afghanistan is nearly complete. But not everyone is happy about it. Some Democrats and Republicans, as well as our European allies, have grave concerns about what will befall the country after the U.S.-led coalition is gone. And former President George W. Bush is one of those.

Bush, in an interview with the German news service Deutsche Welle, said that withdrawing American and NATO troops from Afghanistan is “a mistake.”

“You know, I think it is [a mistake], yeah, because I think the consequences are going to be unbelievably bad,” the former president said.

The war and the U.S. involvement in the country began just a few weeks after the 9/11 attacks during Bush’s presidency.
