Yes, but the break up of theUS, if (when) it happens, is an event that will happen over decades, not years. Historically, that's how long it took empires to collapse.

Who's going to be a credible to alternative to the US in this case? The EU? They find it difficult to keep themselves together. Japan? Too much bad blood with the rest of East and Southeast Asia to be a tractable solution.

America, flawed though it is, appears the only credible counterweight to China right now.
