Nonsense.
The natural resources, manufacturing, services, talents, research, and skilled people in America will NOT collapse, whether there is a nuclear attack on America, a stock market collapse, or any other major calamity.
Kill ten major U.S. cities and the U.S. will still have the largest economy on this planet. Next, kill our stock market and the U.S. still has the most powerful military on this planet.
The plain truth is that only a full-scale nuclear attack by the entire Russian arsenal could endanger our nation or economy on any fundamental level, and the Russians see Islamic rebels in Chechnya as well as Communist Chinese as FAR bigger threats for their nuclear arsenal than the U.S., the largest market for their biggest export market: oil.
So I strongly disagree with you that we are one major attack away from collapsing. We can enforce the value of the Dollar at gunpoint if necessary. We have the guns and we have the Dollars. Simply put, the U.S. is not going to collapse.
