I recall any hippies since back in my day. As for Bushes war, I assuming you are talking about Dubya, he was 100% correct to go into Afganistan, his huge mistake was putting that conflict on the backburner and invading Iraq, very stupid move. Most had no problem with Obama reducing the involvement in Iraq and making Afganistan the main effort as it always should have been.
It is way past time to get out of both countries other than diplomatic efforts, and when trump said he was going to do so I was supportive until he gave his timeline which was ludicrous and I realized he was not doing it for the military but purely for political reasons. My hope is Biden will get us out of the region but do it in a way that is safe for our troops.
The finished product well end up leaving Afganistan in the hands of the Taliban and Iraq as one big mess, not sure we did more good than damage, only history will tell.
