I think it is an important part of U.S. democracy because it contributes the the U.S. in a major way. The creators of the U.S. Constitution worked to ensure the military would be under civilian control. When they wrote the Constitution they separated the responsibilities for the military, placing the responsibilities firmly in civilian hands. Congress has the power to declare war and to make the rules for governing the military. There are some disadvantages, though. The American Civil War of 1861-1865 was the period of greatest danger to civilian control of the military. As the war progressed, more and more people called for a military dictatorship. Military officers stayed away from politics and many even refused to vote, feeling that this would somehow influence their service.
Government and society in China were grounded in the Confucian philosophy, which held that there was a basic order in the universe and a natural harmony linking man, nature, and the cosmos (heaven); it also held that man was by nature a social being, and that the natural order of the universe should be reflected in.

Access to food, water, shelter, and all basic human needs can hinder or help the growth of a civilization. Civilizations with similar environments or climates tend to develop on similar paths (because they run into the same problems/conveniences that have to be solved by human brains, which are wired to react to certain situations in certain ways.)
