Biden and trump both wanted to end our involvement in Afghanistan. trump haphazardly went ahead on his own , ignoring his advisors , excluding the peace negotiating team altogether ( destroying years of work ) , did not include the Afghan government in his meeting ( which helped lead to the rapid decline in their power and the eventual collapse of their government ) and gave the Taliban everything they asked for. None of this worked out in our interests or that of our allies in Afghanistan.Maybe you post the agreement Trump made with the Taliban that they can keep billions of dollars worth of military equipment.
