Oh god, so much wrong in this post.
"That's why we have influences in countries such as Afghanistan" - Earlier you said America is the best country in the world, now you admit you're invading a foreign country for oil, killing hundreds of thousands of innocent people.
"Russia couldn't even defeat Afghanistan" - Holy s***, this is a eye-opener to how many Americans are brainwashed by war propaganda. Firstly, Russia have never even been to war with Afghan and their care cup isn't even 1/10th full when it comes to America and their bullshit excuses to invade. Secondly, China is the fastest rising super power in the world, and no, not just because of their population count. Do research on that, as I can't be bothered listing why. Lastly, look how war, death, destruction and devastation is seen in the eyes of an American adolescent (generalising, not all are the same). "They can't even beat X", like it's a game. War isn't a game, it's sick and illegal.
"China and Russia's militaries are both inactive, and have been for quite awhile now, while we have been fighting in many wars and saving many countries.. We could easily rule the world if we wanted to." - Ladies and gentlemen, the average American mindset.
