As long as China and Russia remain peaceful and don’t threaten their neighbors with aggression, they can absolutely win the war for hearts and minds and thus assemble a broad coalition to buck the US’s interests. The problem here is that Russia has already invaded its neighbors and proven to be a security risk for Europe, while China is doing everything it can to signal to its own population that war with Taiwan is imminent and to its neighbors that it’s a major threat. Maybe they’re all joking (well, except for Russia) but the very real security threat posed by China and Russia to their neighbors puts an upper “cap” on the effectiveness of a broad anti-US alliance. The backstop of US dominance isn’t feelings, it’s the global desire for survival.
