Donald Trump pointed out that it was not the job of The United States to police the world so why should the United States be policing Afghanistan? There was no war in Afghanistan. Congress never declared a war in Afghanistan. And even if it were there are plenty of other countries that would be more beneficial to police like China, Russia or North Korea. Of course someone was going to take the blame for the disasters in the Middle East and that gives Jim Crow Joe another failure to add to his list. But it's not like The Middle East was in a good state to begin with.
