Victory Disease

There is an interesting idea being floated around called Victory Disease. In essence, Victory Disease means that what goes up must come down. Whenever an individual or group makes a major military victory, they can be so overcome by hubris that they consider all their adversaries to be inconsequential, which leads to some disastrous consequences. Some famous examples of this include Napoleon at Waterloo, or more recently the U.S. at 9/11. The U.S. was so full of itself after the “fall” of Communism, that it did not consider Islamic militants in the Middle East to be much of a threat.
What I will be talking about next is a concept of my own devising, and any and all comments are welcome. The U.S. used to be what one could consider “up.” However, now we are going “down.” The signs are unmistakable. China and Japan have both been making considerable leaps in the international market in recent decades, U.S. currency has less and less value when compared to other currencies, and our political structure is being weakened from within. I could expound on these topics for several more pages, but you get the idea.
So, how do we, as patriotic Americans, avoid this? Well, the only way to stop from going “down,” is to get rid of our enemies completely. The only way to do idea morally is to make them our friends. The only way to make such alliances permanent is to absorb the other nations into a single, conglomerate, world-wide nation. This step would involve many benefits to all of mankind. However, what I would like comments on is how we can do that. What can the president do to do this? What can the U.N. do to do this? etc. tell me your ideas
