Throughout the years the United States has been involved in many different wars. Starting with the Revolutionary War (1776) when residents of the 13 colonies revolted against the British, we have been at odds with other countries (and ourselves) ever since. Who can forget the Spanish American War, the War of 1812 and of course the Civil War, all classic wars fought in the 19th Century. More recently, this century has seen World War I and World War II, shining examples of how countries throughout the globe can fight one another.
