America will be replaced as a unipolar world power, it's a question of simple mathematics and economics and time. You'll get over it, same as the Brits did last century.

Instead of doubling down on paranoia of the foreign 33-dimensional chess player[1], if you want the US to strengthen itself, look at dealing with its internal enemies and problems, as opposed to clutching pearls at external ones. All of our injuries are self-inflicted.

[1] I'll note that the Department of State isn't stupid, it plays similar, long-planning games that you ascribe to foreign powers.
