Difference, though, is that those countries were not great military powers, much less superpowers, much less the world's only superpower.
I shudder to think of a world in which the United States is unable to project its superior military power.
That said, if the split was a "virtual" one -- where, because of a return to federalism, states were allowed to reinvent themselves in their own image -- the union would be preserved and the one great task of the federal government would be to focus on national security and military defense.
The USSR was a superpower.

Russia is still the second most powerful military power even after losing the other 14 states of the former USSR.

That could work.
