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.
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
