Let me finish the thought ...
intent on the destruction of the American representative republic and replacing it with a Stalinist government run by themselves
I agree, except for this line:
replacing it with a Stalinist government run by themselves
It is my understanding that Stalin was an "in house" communist, i.e., the Russian brand. Whereas, Trotsky is the premier symbol of international communism. Permanent contiuous communist revolution. I would say our Dimocrat party are more Trotskyite than Stalinist.
