Like, giving independence to California and Cascadia for example. Because if you’re a communist party and believe the US is a settler state, it’s logical to strive to break up that state. But I’m not Statesian so I don’t know in what way this is discussed in the parties.
But the USSR recreated the nation states that made up imperial Russia and gave them full rights to secede, have their affairs conducted in their own language etc. Russia used to be one big blob before the USSR split it into many socialist republics.
They did do that and were right to but to me that’s not “balkanization”, it was a federal union with a shared foreign policy and economic/political infrastructure.
When I hear balkanization I think of like the collapse of Yugoslavia or the USSR in 1991 for that matter, which was just miserable for everyone involved except the nationalist mafiosos like Yeltsin
