I think a more likely outcome is nobody filling the hole America leaves behind, and the incentives of a multipolar world are much more brutal then that of a unipolar world, as a result I expect a rise of new nuclear armed states.

But I do believe that is why Americans are so frightened of a multipolar world (or really, any world where the US isn't the singular superpower).
