The U,S, hasn’t won a significant war since World War II, but a lot of people in its government think it can dominate the world. From Marc Sills at unz.com:
Nothing Lasts Forever

In February 2025, the first full month of Donald Trump’s Second Coming, the new Secretary of State Marco Rubio is asked what he thinks of China’s assertion that present and future international relations should be conducted within the framework of a “Multipolar World.” Rubio accepts that terminology, but his interpretation is not at all the same as China’s. He dances around the issue and equivocates that multipolar world systems sometimes do happen, in the course of political history – and so do Great Power rivalries, and so do “abnormal” unipolar systems, in which one state or empire, like the United States, enjoys hegemony over all the others.
China advocates for equality among state actors. China stands opposed to American hegemony. China, along with most other states and their advocates, wants a multipolar, multilateral world system ordered by International Law, and mediated within the United Nations. In response, Rubio (representing Donald Trump, of course) launches into an entirely spurious claim, without any compelling evidence, that “China wants to be the most powerful country in the world and they want to do so at our expense, and that’s not in our national interest, and we’re going to address it.”
Rubio emphatically insists that Uncle Sam needs to prevent an entirely fabricated nightmare fantasy from happening, by force if necessary – to defend the “Homeland,” and its many far-flung “national interests,” and the “Free World” at large, from the Chinese menace. Rubio wants a world divided by “spheres of influence,” in which one nation – the USA, not China, and not Russia – reigns supreme over all others, and really does ultimately control the world, by military force, presumably forever. And the world is just supposed to submit to that control – also forever.
