I don't know much about Anglo-American history, but the movement might spread south into Latin America (were workers had already ) leading to a US surrounded by Communist states.

I do believe, though, that since Trotskyism was very important in L. America at the time, a rupture with Canada or together with Canada against the USSR might occur.
