Step 4: Normalization. The troops are being programmed that the enemy is the People. https://youtu.be/yErKTVdETpw
In the wake of Vietnam, and the end of the draft, the US Military looked to a smaller active force with an increased reliance on reserve and national guard forces. A major factor that figured into this thinking was that a large standing military of conscripts (generally those that could not, or would not get around being drafted) was detached from society and this in turn led to the unpopularity of the Vietnam war.
The thinking was an increased % of guardsmen and reservists would seed servicemembers throughout communities in the U.S. and would engender more support in the event of a large scale mobilization. Few people cared if the high school dropout or troublemaker got drafted and sent overseas with faceless others from around the country, but when a local high school teacher, car mechanic etc. that people knew got called up, the community would be more inclined to support them. Indeed, this thinking seemed to play out to a degree during Desert Storm.
But now, it may play out in reverse. These guardsmen will at some point, have to go home where people know them, and whatever they do, or don't do in DC is going to go with them with the full knowledge of the community to which they are returning. I hope and pray, for their sake and the nation's, that they can go home quietly, with their honor in tact and nothing more than a few photos of DC to show their kids and a few extra bucks in their pockets from this deployment.
