There's a saying: the dying serpent always bites. Empires usually die a slow death by overextending themselves in war.

I wouldn't be too worried in this case though, the economies of the US and the PRC are so intertwined, that US capitalists have more to lose than to gain by starting a hot war. The war hawks know they only have a few more years of military (specifically naval) superiority, which is why they make a lot of noise that it's now or never. But the PRC thankfully played the long game, and even accepted some trade deals that weren't in its favor, in order to tie their economies together, to prevent war.
