Sign 1:
Historically, one of the signs of a decline of a civilization is the belief that we (the United States) can expand and dominate a large part of the world with our culture and beliefs. This is impossible, yet we (the United States) show every sign of attempting to bring it about.

Sign 2:
The other sign of the decline of a civilization is national debt, and the United States has more debt than it can ever repay. The truth be known, it isnít expected to repay it; itís only meant to keep us in poverty as financial slaves. Most of our (US) debt is interest on pre-existing debt. The only way this can go on is if the citizens continue to believe what is told to them.
