Complete control? Probably not. However, I have never met a liberal, Hillary-voting Gunnery Sergeant, Senior Chief, or Master Sergeant. Never. A substantial majority of junior and mid-grade officers are also patriotic. It's only once stars show up on the shoulders that there is a selection bias toward lacy-panty globalist traitors. The military will not be able to oppose real Americans if our domestic enemies start a civil war, and a large chunk of the military would be sympathetic to following the Oath we all took.
President Trump must immediately take measures to assure that all officers and the Joint Chiefs of Staff are patriotic Americans! That is vital!
