The United States of America is the most powerful nation on Earth. Period. It's not even close. We spend more on our military than the next eight nations combined. Our troops are the finest fighting force in the history of the world. No nation dares to attack us or our allies because they know that's the path to ruin. Surveys show our standing around the world is high... When it comes to every important international issue, people of the world do not look to Beijing or Moscow to lead; they call us.
