Not even the military can be trusted. Generals and Admirals get to be Generals and Admirals by buying into the Communist mantra. Sure, the military will be split, depending on who obeys orders. All the better for the traitors. Fighting among ourselves will only embolden China and the Communists.
No, the battle is going to be whether the patriots amongst us rise up and defend our freedoms.
Sadly, I don't believe they will. There will be pockets of resistance but no coordinated effort. Those pockets will be vilified by the MSM and identified by big tech through the use of location tracking. Local LEOs may decide not to help, but federal LEOs will do their masters' bidding. The media by line will be that federal law enforcement is tamping down on "right wing extremists."
I don't believe Republican governors have the stomach to muster militias to help in any attempt, not at the risk of pissing off fed gov, and any resistance fighters in Democrat strongholds will be sniffed out quickly and extinguished.
We need military tacticians who are skilled at subversion. This won't be a ground conflict. This will need to be done more along the lines of what you saw in Mr. Robot. All they have is information warfare. If we can subvert their lines of communication, we have a chance.
