It is difficult to see how the present troop force in Afghanistan would be able to accomplish what one nearly seven times as large could not. According to an in-depth investigation conducted by BBC News reporters in late 2017, the Taliban fully control four percent of Afghanistan’s districts and “have an active and open physical presence” in 66 percent of the remaining ones. There are currently fourteen thousand U.S. troops stationed there, up from 8,500 when President Trump took office, and the Army is recommending that the president authorize the deployment of an additional one thousand troops.
