Do you think a power imbalance or global revolution as the other commenter implies is more likely to occur than another hegemony?

If they suddenly closed prisons I wouldn't be like "hell yeah, in a just world we wouldn't need prisons, nobody should have their freedom taken away." I'd be preoccupied with what I think is going to happen in this world.

Also, every single country engages in "imperialism." It's basic geopolitics. Simply trading with people gives you influence with them that you could potentially leverage. (Remember, this topic is about soft power and influence, which some people are calling imperialism. If it's confusing don't blame me.)
