So much of American "power" in the past few decades has been based on perception, not reality. And other major powers, including China, have largely played along because it has suited their interests too.

Of note: the US doesn't even have an aircraft carrier in the Pacific right now. The only thing keeping China from, say, moving on Taiwan, is Pete Hegseth's testosterone.
