And how would an American soldier have the opportunity to do the same if they were not afforded the same opportunity?

"Opportunity" is not the same thing as "being given a leadership position in a small leftist organization during a time when armed combat is not required". Zhukov and Chavez had to earn a lot of trust with their lives on the line in combat to get to where they were, especially Zhukov.

I mean not to demean the extent of American war crimes..... However

A few decades before that the americans had already ethnically cleansed north america. The russian empire was rightfully destroyed by the Bolsheviks while america still persists. Point being that american soldiers as part of a settler colonial ethnosupremacist anti communist military force are heavily indoctrinated to have deeply held reactionary beliefs. You dont have people like that anywhere near leadership of a communist org. Especially small ones that aren't focused on combat at the moment. Why do you have to have former fascist shock troopers leading a workers organization that is meant to fight for the very working class who the leader has oppressed and marginalized? Why should workers have to rely on their oppressors as the rightful figureheads of their liberation?

I'm saying there are plenty of people who are disenfranchised by the military who go on to train and lead revolutionary forces

How about learning from the people who the us military lost against and/or who have experience fighting them. Veterans can act as trainers but they shouldn't be let near leadership positions for the same reason you don't want "former neo nazis" in positions of leadership either.

You can still disdain the military without disdaining former soldiers who learn class consciousness and now also disdain the military.

Yeah but it's fine not to especially for those who are oppressed by the us military. And for good reason. Look at how the former navyman itt reacted earlier to someone expressing rightful disdain towards the genocidal us military. Not saying he can't change for the better, he should, it's just that he's one of the most politically advanced amongst them.

If there is a revolution in the imperial core, you can guarantee that former US military will be involved.

Yes as the counterrevolutionary fascist paramilitary sent to kill the revolutionaries.

I'd rather there be a successful revolution

Surely a successful revolution would be possible without having "former nazis" in charge.
