war is a very disastrous thing in the world. parts of the world are struggling because of war. a lot of towns can get destroyed.
war sometimes starts because one piece of land wants to take over another piece of land. you can never have to much land. only one piece of land can win.
every piece of land needs someone in charge. there can be a vote. or sometimes someone becomes a dictator which is a unfair ruler. rulers can also be over run.
