Introduction Former American President Jimmy Carter said in 2018 that in America, there were 226 years of wars since its independence which took place 242 years ago thus leaving only 16 years of peace. Since WWII, there were 32 American military conflicts involving dozens of countries. Some of these military conflicts have lasted for over twenty years and some others are still continuing. In other words, the U.S. is a country of perpetual war. War is terribly destructive human activity.
