I think it's better for the US to shatter, than for its continuation as a geopolitical threat to the peace of Afro-Eurasia and Latin America, and its survival as the bulwark and champion of settler-colonial ideology.

Humanity can push its luck once more, or a dozen more times, and it would still likely be better than the continuation of the continental USA, which in and of itself- even without its foreign bases and territories- is undeniably an empire. A unified North American behemoth, one built upon such wretched foundations as the US, has to be contained, or better yet, shattered, for there to be any sort of lasting peace, IMO.
