Some points are reasonable but

this post seams forget that the States is the most powerful nation for keeping peace in this world. USA does not like a war with China, or Russia, but is making every effort in keeping the world peace. There is doubt that there is a long march to go for any nation to exceed the States as the largest economy, because She has too many advantages compared to other nations including Jps, Russian, Germany, and China. It is these advantages that attract intelligent peoples all of the world to move to the States, that is the engine to drive USA to move much fast in terms of economic, social, and high tech than the other nations.
