evidence: Three years ago this week, the U.S. withdrew from Afghanistan. It was a dangerous and chaotic exit. Thirteen troops and many, many Afghan civilians died. Former President Trump has laid the blame squarely on President Joe Biden and presidential candidate Kamala Harris. We wanted to talk more about some of those charges. Here to help us out are NPR Pentagon correspondent Tom Bowman and NPR's Quil Lawrence, our former Kabul bureau chief. Welcome to both of you. [...] LAWRENCE: And just to fact-check one thing former President Trump repeated yesterday - that, during his presidency, there were no casualties in Afghanistan for 18 months. Trump's been saying this for years, and it's just not true, according to Pentagon records. [...] LAWRENCE: There is a lot of failure to go around to the four presidents over the 20 years of war. Trump was clearly interested in ending American entanglements overseas, and Biden wanted out of Afghanistan, too, since as far back as 2009, as Obama's VP. I can say I watched on the ground. From about 2005, the Taliban started gaining territory, and they did so for the next 15 years. At the end, when Kabul fell, it was on Biden's watch. All the intel reports at the time suggested that the city would stand for a few more months. Friends of mine in Kabul told me they expected that, and they didn't flee. In hindsight, it was a massive intelligence failure.
