Kabul has fallen. While this was expected to happen, the U.S. government has been surprised by how quickly the Taliban took over.

At the start of this week, there were as many as 15,000 Americans in Afghanistan. Now, Americans, along with thousands of Afghans, are trying to flee the country. The result? Mass chaos.

This week, panelists Josh Barro, Liz Bruenig, Megan McArdle and special guest Paul D. Miller spend the entire show talking about the war in Afghanistan. Why did the war continue on for so long and what was the U.S. trying to achieve? Was there a better way to withdraw that posed less risk to American personnel and provided more evacuations of vulnerable Afghans? And what should we do now? We discuss.
