You don't give a damn, probably most of your countrymen (assuming you're from the US) also don't give a damn. And there's probably over a billion Chinese that don't give a damn that you don't give a damn.
I don't wish for the US to lose their global influence either, I rather like what I get out of that. But I am under no delusion that this is a lucky happenstance and that the interests of the US could change to ones that I am not happy with, and that China, and any other nation will have their own interests that they pursue; Within their moral codes, within their systems of values, interests that we here may judge as wrong or counter to our beliefs, may well be the opposite and acceptable in their origin nations.
So if you want to interact with those nations in any fashion, you need to throw away some of these notions of morality, or at least reify them to things that are relatively universal, of which there aren't as many as one would think on a geopolitical scale. You say that we need to consider where we come from and where we're going. I say that we cannot do that in a vacuum, so if you want to really understand, you have to understand the other side too.
