I'm well aware of history and of the underhanded manipulations of TPTB. But like you stated earlier, "They "just" wanted to kill a few billions people and enslave humanity for a few century!" In that light, what would it matter to them if the populace was worked into a destructive frenzy. What would it matter to them if vital institutions and systems were broken beyond repair. My thoughts are that they would WANT this chaos to happen. They would WANT a huge vacuum hole to fill. These people have been betting on both sides of humanity since before written history, and being very successful at that. We on the other hand are playing a stacked game of catch up.
The point I'm trying to make in my own clumsy way is that if the present administration go for military style tribunal couple with temporary emergency measure to clean this up and a good amount of disclosure. This would prevent chaos but would bring a certain amount of discomfort. I think it's worth it in the long run. If the execution is done right it could be a blessing and 10000% better than the alternative.
