It was a mistake when Bush started it -- or at least continued it after bloodying the nose of the Taliban -- and it was a mistake when Barack Obama rubber stamped Bush's policies and continued our involvement in Afghanistan for eight more bloody damn years.
It was a mistake when Trump did not get us out of there during the first term -- although we gotta admit that NO president EXPECTS to have a bogus witch hunt style investigation launched against him followed up by TWO bogus impeachments for strictly partisan political purposes.
And it was a MISTAKE to have a known dementia patient president -- famous for always getting all foreign policy decisions wrong -- to be the one to finally conduct the withdrawal while give the nation to the enemy Taliban and while totally re-arming them in the process with cutting-edge weaponry.
