> If you've been teaching swimming exclusively on the blackboard for 20 years it's probably time to retire as a teacher - your students are never going to learn how to swim from you. Yes, but sticking to the analogy it says more about you as a teacher than about your students. I think we can agree the US failed pretty badly here to get the Afgans into shape to defend themselves. They shouldn't have left until they achieved that goal. They were down to just 3500 soldiers. Hell they have a bigger troop presence in Germany, and dozens of other countries around the world. The death rate is comparable too, believe it or not. The last soldier to die there was back in 2020. There was no need for this rushed disaster.
