There as some many perfidious actors in both the Deep State and contractor world that it seems almost Sisyphean to defang them. These 40-something retirees from the military and intelligence communities that hate Trump and will do anything to make the world safe for Davos and their six-figure consulting gigs (on top of six-figure government pensions).
