The fact that the U.S. remains the world's preeminent economic, scientific, and military superpower despite the fact that most of our population is compromised of ignorant morons is a testament to the nation's greatness. I'm not ashamed of my ignorant countrymen, but maybe the rest of the developed world should be ashamed that they have failed to knock the U.S. off the pedestal, given their apparent intellectual and cultural advantages.
Well, it's hard to counter that argument, because it is not really an argument at all. How do you compare these things? GDP, SJR, Military Budget? If you do so, do you include the EU as a power, or do only political countries qualify? Also, if you really want to be fair, you have to compare these things per capita, and I'm afraid that if you do so, USA will not be first in any of the three categories by quite a margin.
But spoken in total values, you are correct, of course. USA is just a damn big country, so it's not really that surprising.
