I don't know what that has to do with anything. But it's interesting that you think Soviet Union had megacorporations exploiting other countries for superprofits and did it even better than current megacorporations.
That's why Eastern Block suffered from food and other daily usage products shortage. In fact Russians suffered the same due to massive waste, economy inefficiencies, continuous arm race with the West and madman project like White Sea-Baltic channel (Belomorkanal), agriculture "inventions" by Lysenko and thousands of similarly idiotic ideas.
"Imperialism was both normal and common worldwide throughout recorded history, the earliest examples dating from the mid-third millennium BC, diminishing only in the late 20th century."
I am not aware of any capitalists or corporations predating the Iron Age, but perhaps you can enlighten me there.
> Also capitalism implies imperialism, not the other way around.
I would disagree that capitalism implies imperialism, but let's put that aside. My claim was exactly that imperialism doesn't imply capitalism, so I guess we agree on that? Non-implication is not exclusion, mind you. The Soviet Union was imperialist, but not capitalist.
Having said, that, I'm sure there is a fruitless debate to be had with those Trotzkists that would claim that the Soviet Union was imperialist, capitalist and fascist[1].
