"The militant commander at the center of the concerns in Helmand Province is a prominent former Taliban leader, Mullah Abdul Rauf Khadim. He was detained at the Guantanamo Bay military prison for several years, then returned to the Taliban ranks after his release, serving as a provincial-level military commander.." 
In other words the Americans turned him into a Covert US Agent at Gitmo and then released him to return to Afghanistan in order to do their dirty work for them. Otherwise, why would the Americans have released him from Gitmo? Out of the goodness of their heart? Do you think the Americans are stupid? It is the same pattern of behavior we saw with the ISIS Founders in Iraq. They were all detained at Camp Buca where they were turned into Covert US Agents and then released to do their dirty work for the Americans in Iraq and Syria. Otherwise, why do you think the Americans released them from Buca? Out of the goodness of their heart? Because they are stupid? No!—on all counts. The Americans know exactly what they are doing and why they are doing it.
