I agree on both points.
Addressing the second, the change has not happened. But it is and has been a work in progress whenever the Dems have the upper hand. The Clintons drove out some of the good career officers, Obama is doing the same now as well. Their goal is a gradual rotting from within the military. IMO, that is their desired and defined goal, not an unplanned result of misguided policies.
It is analogous to salt water seeping into a freshwater aquifer. One day you go to the well and it is no longer potable. It happens slowly.
Agreed
