If course I wouldn't be here. And you wouldn't be here. And every person that is alive on this planet right now wouldn't exist. It would be an entire different world, different technologies, different countries, different whatever, because that's indeed the result of the hypothetical situation when something like an entire country wouldn't be there. And if I travelled back in time in this hypothetical situation I wouldn't even pop up in WWI or WWII since history would be different. But the world would still be turning.
The US is a great country and people can be proud. But claiming you're the best country on earth, leading by example and being #1 in the world in everything is not only living a lie but an insult to the rest of the world.
Is the US a nation without racism, crime, with healthcare for everyone, with equal chances for all? Are you fighting hunger, global warming, poverty in your own country or in the world? Are you the only country with freedom? Is the Us going to war in other countries to bring them unselfishly freedom? No, you're not better than the rest of the planet. But what you have is power, both economically and military. And both are used for gain and profit, not to bring freedom and to show the world why your country is a "leading example". And as long as this misplaced chauvinism keeps insulting the rest of the world you're going to have people burning the US flag and tell you to fuck off, while some American cries on television "But I don't understand, we're bringing them freedom, why do they do that to us?". But keep living a lie. While people like D-rock are aware his nation has faults and it needs to improve, chauvinists like you are just standing in a circle jerking off to the flag doing nothing. At one point you might wake up and see China owns you, and your industry and infrastructure in your country is getting old, and more and more scientists from other countries do have the top positions in your tech industry and universities, and so on. Your empire is crumbling.
