To learn the right lessons for future foreign policy and military decisions, we must reanalyze not just what the United States did wrong in how it left Afghanistan, but also what was wrong in deciding to leave at all.
The decision to leave Afghanistan was made, ham-handedly and tragically, by former President Donald Trump and confirmed with feckless and even more tragic operational follow-up by President Joe Biden. Every sentient person should be unendingly furious at Biden, his Cabinet, and the top generals who completed the retreat and defeat without rescuing all Americans who wanted to leave and while Biden failed to honor a law requiring him to report to Congress in advance of his withdrawal plans. The behavior of Biden and his team is a monumental disgrace, the worst diplomatic/military conduct of my lifetime and perhaps in all of U.S. history. Mass resignations are in order, but apparently, these people have little sense of honor.
