Here's something to think about, "Who would be wearing those blue helmets ?"
It will not be Ukrainians, or Pakistani's, it will be American Troops and cops. They aren't all "Oath Keepers".
If it were to come right down to the line, are you prepared to shoot a US soldier, or cop, regardless of who's orders he is following.
Not only are most unprepared for that but they never will be. Gangs of looters we will shoot at, put them in Blue or Camouflage and suddenly they are irresistible.
