OK, after searching around, it’s this thread.
The OP of that thread is a veteran of the war in Afghanistan and appears frustrated with the lack of progress in fighting off the Taliban there. And I can’t say I blame him. He’s just one of many people who was sent there to perform a mission that seems unattainable, to say nothing of the Afghan residents already there who have to deal with the fallout.
I’m 35, so I was in high school when 9/11 happened. As far as I have been able to discern, the only reason we ever invaded Afghanistan was in retaliation for 9/11. Osama Bin Laden was supposedly hiding there, and the Taliban was somehow affiliated with the people who attacked the World Trade Center, so we had to attack them. OK, I get that. “You hit me, I’ll hit you.” The concept of regime change did not and still does not make sense to me. If Russia could not impose its will on Afghanistan, I don’t think anyone can.
I empathize 100% with veterans of the war there who feel like the country has given up on their mission, just like I understand the way so many Vietnam veterans feel. But, as with Vietnam, I think we should have cut our losses a long time ago rather than continuing to dig in and get more people killed. I’m no expert on any of this, I’ve never served in the military, I don’t think any group of people can be categorically called cowards. The blame, as usual, seems to lie with the policy-makers at the top who never have to face the life-and-death consequences of their decisions.
