America's destructive capabilities reached their final form in the melding of money and ignorance under Bush. The legacy was the near collapse of the world economic system and the catastrophe of Iraq and the Middle East. America cut its teeth by informing Hitler's racism and causing the Great Depression which enabled Hitler's takeover of Germany.
Money and racism are America's evil. America was not a nation of evil people but the evil elements, a laissez-faire wealthy class with no social conscience and southern racists, were able to seize power. The world got drug along in differing degrees. Global warming knows no bounds. Neoliberalism infects other societies. America is destroying the world.
The world will survive. The American way of reckless waste and compulsive living will not. By its nature it's a boom and bust system.
