This is about as close to the absolute truth as you will read on the topic.
No effort short of the overwhelming use of armed force has ever stopped a left wing movement after its initial outbreak of revolutionary armed violence.
We've had two previous leftist revolutionary movements in the United States.
The first was post-WWI when European immigration brought socialist and anarchist violence to our shores.
The Palmer Raids of 1919-20 ended with the deportation of 556 (kek) violent socialists and anarchists back to Europe.
The FBI went on a rampage and practically destroyed the Socialist Workers Party, Industrial Workers of the World, and Communist Party USA by arresting their members. In short, it was disrupted by a coordinated whole-of-government anti-communist effort.
Then you had another iteration of revolutionary leftist violence in the 1960s and early 70s. Again, it was infiltrated and toppled by the mid-1970s, because of programs like COINTELPRO and other federal law enforcement efforts. (Bryan Burrough tells this story in Days of Rage, btw.)
So here we are, at the precipice of an incipient third iteration of far left revolution.
Were the administration to understand just how serious/late the situation is, I don't think it's too late to stop the movement prior to a Herculean use of force.
But if the Trump admin continues to ignore them and lets this thing fester, we will have to deal with the consequences in 2029+. (This is why I constantly criticize the admin's lack of action on this.)
Kind of like the saying, "you can vote your way into socialism, but you have to shoot your way out," all of modern history shows:
You can disrupt a far left revolution in its early phase, but you have to use armed force to defeat them once they get going. There is no other way.
Unfortunately, the lesson of history is there is ultimately no stopping the Left except with the methods of Franco. The Left, like the Terminator, never stops unless forcibly stopped; for it, any pause in the revolution is impossible. Sorry, I don't make the rules.
