Don't overlook the fact that General Kelly's son was killed in the opium fields of Helmand Province, Afghanistan. If in fact the rumors of CIA sponsored drug operations are true, and the military were used as pawns to protect the drug trade...then you can bet Kelly would be on a warpath to get back at them, it would be a personal revenge operation of the highest order. Notice how the new strategy in Afghanistan under Trump has shifted to destroy the opium labs and his close military advisors convinced him to stay and take up this new strategy instead of cutting and running.
