It's not really the US not needing to de-escalate so much as the US refusing to engage with China in good faith. They don't want to de-escalate because American exceptionalism and the influence they wielded since the collapse of the USSR has rotted their brains. Quite literally unable to see the current state of the world as anything but a zero sum game.I mean saying US doesn't need to deescalate because it so strong etc etc is straight up debunked multiple times over already.
American nationalists were saying this as far back as pivot to Asia or Trump trade war. Saying "we can review this conversation 3-5 years in the future" and that America will finally stop being scared and escalate.
It has already been 3-5 years, and then 3-5 years again since then.
US political elites, economic oligarchs, generals, admirals and officials get cold feet, somehow only high bravado nationalists that get their news from fox and epoch times don't get cold feet.
I hope to see countries cooperate, get rich, and address climate change but that ain't ever happening because of fundamental ideological and economic conflicts of interest.
