So you think that large wars are over and that we can defeat China and fight on multiple fronts, perhaps in Europe or North Korea with technology and to heck with manpower and troops?
The U.S. will never fight a war against China, just as we never fought a war against the Soviet Union.
The U.S. will lose those wars before they ever start, because our enemies will simply make their way into the highest reaches of the U.S. government. Where do you think Barack Hussein Obama came from?
