The crisis is coming. How will you know it’s here? When Trump unleashes the might of the military and federal law enforcement against American citizens whose only crime is to oppose him.
What will cause the crisis? It won’t happen until Trump feels threatened by the opposition. When will it occur? When the threat becomes intolerable to him, and when he is certain of the unconditional loyalty of the military and law enforcement. That could be as late as the 2028 election. But it could be earlier–around the midterms or in response to an unfavorable Supreme Court decision, a mass demonstration, effective blue state resistance, a self-created financial crisis, or a dangerous international event.
How will America react? TBD. One thing is for certain, however; history shows that a ruthless and single-minded minority with guns can get what it wants even against the will of a large majority.
