Find it yourself. But if you google it, the only thing that will come up is how it’s Trumps fault. If you DuckDuckGo it comes up mostly Trumps fault but Biden is to blame too (but hey! knucklehead bush started it.) If you where watching the news at that time when Tump made the agreement with the Taliban for an orderly withdrawal you would understand. Then Biden ordered troops in and air attacks, violating Trumps agreement. You might find the stories in Other than Main Stream Media.
