I just think it would be pretty bad if a nation like China or Russia took charge of the world, due to their history of authoritarianism, manipulation and crimes (sometimes against their own people). And without USA, that is what inevitably would happen... EU doesn't have enough strength to fight from equal to equal against the eastern axis.
Regardless, I don't think it's much different when a big country has influence, it can be bad for smaller countries, but it's a risk.
Now we can see that the US is still at the top of the global economy today is that good for smaller countries? of course on the surface it looks good because the way the US does it is different because they prefer to extract little by little under the pretext that they are the ones who can make the economy better but in the long run in the end the intention is not too far away from other countries such as China, it's just that the actions are a little different because the US prefers to make it seem as if they are saviors not enemies but as much as possible get overall benefits even if slowly.
That is normal because after all when a superpower like the US and China then they will do anything to show the gap and ability because they know it can be one of the characteristics that they are a powerful country.
