There has never, in the history of the world, been a country that has amassed as much power and wealth as the United States, or used it for as much good as the United States. In short, the United States is the greatest nation in the history of the world. According to John L. Perry (go the the above link) however, history demands greatness of great nations, and history's patience just might be running out on the United States.
According to Perry, "No nation in history....has given, gladly given, of its own riches to feed the hungry, clothe the destitute and heal the stricken as much as has the United States." We have openly and freely invited others from around the globe to join us, assimilate into our "melting pot," and enjoy "the blessings of liberty to ourselves and our posterity." We have become great because we have strived to accomplish great things.
Will this continue to be so? I don't know. The column authored by Mr. Perry raises interesting points concerning that very question. Read it and see what you think.
