> The U.S. still has competition from Europe and China, no?
Not militarily, at least not the way the Soviets were competition.
If the US really is on the Roman path and transitioning from the republic to the empire, it's not clear Europe + China have enough force to keep MAD in place.
Europe + China have between 500-750 nuclear weapons usable on short notice. Depending on how well classified US missile defense programs work, it's possible for the US to only lose a single digit number of metropolitan areas.
Combine this with the fact that large, dense urban areas primarily contain the current administration's political opponents, and that may become acceptable losses.
A potential alliance between the US and Russia being on the table (or at least a non-aggression pact) further bring a non-MAD world order into the range of possibilities.
