Obviously, United States of America has it all: military/army superiority, largest economy, size of population and land mass, educational standard of most people, and their technology advancement. These are some reasons why USA is such a powerful nation.
Military/army superiority?? I guess I can't argue that
largest economy? Yeah.... not! Our economy has been declining for quite some time.... you realize we are still climbing out of a recession right?
size of population and land mass? I don't know what land mass has to do with anything, but China has a larger population then we do.
educational standard? Your serious???? You actually think our educational standards are high?
Technology advancement? So paying other countries to give us our technology makes us more technologically advanced.... interesting concept.
What makes us a powerful nation has nothing to any of it. We are strategically and militantly smart. That is what makes us powerful. Nothing else. We don't have money, our technology comes from elsewhere, and our education is falling behind. Just about every nations peoples think the worse of us because their governments keep calling us in to save their butts when we don't really even want to be there.... I think the US needs to go back to the way we were before WWI and let the other nations fend for themselves for a change. We need to work on ourselves and let the other nations deal with their own problems... but then we would be hated for NOT getting involved in their nations issues.... double edged sword.
