The Civilian Putsch of 2018

Does a dangerous rift actually exist between the United States' military and civil governmental leadership? A considerable group of influential/elite academias believe that such a gap exists and suggest that it pose a dangerous threat to our very Republic. The alleged rift resulted from the following: divergence of cultures, "republicanization" of the officer corps, increased military involvement in domestic affairs (i.e. drug interdiction, disaster relief), the cultural clash between the military leadership and the Clinton administration and the strengthening of the military via the Goldwater-Nichols Act, etc.
