It all depends on what war you are talking about. America has been in many wars, however; it is debatable about how many were actually on American soil... Many wars were fought in America like the- Revolutionary war, the War of 1812, Civil War, even WWI and WWII were partially fought on our land. All of these wars were won by America because we had more military power and more allies to help us when we needed it, we also had enough factories during those times to provide military weapons to supply our military.
