Let's be honest the US hasn't even managed to make itself rule the world for a couple of years from when they had the chance after ww2 to immediately getting humiliated in 2 large scale wars in a row.Oh snap, look at that map! We have DC leading the pack when DC literally produces nothing except rotten lawyers and dirty politicians! That shows American priorities and values.
No, he has learned from getting his accounts banned several times just how stupid he can get before being made to go away so he has actually toned down the stupid by a lot since he first came to the forum several usernames ago. He used to write things like, "The US will rule the world for now and until the sun burns out and the end of time and everything ceases to exist." Being stupid and wrong to a certain point is not against the rules and the mods are happy to come down on him but he's staying alive straddling that line. We're honestly nastier and more inflammatory than him but that's just because the combination of America's comparative decline and his child-level debate skills leaves so many targets open and China's superior performance provides so much ammo for us.
You can only claim to rule the world when there's no large scale opposition to you. Having the world's largest economy and single strongest nation hate your guts and oppose you in everything is antithetical to being "ruler of the world".
