Many are the causes of wars such as theft of important documents (some, if handled without right knowledge could cause great damage), and too mutch corruption in a nation. In the latter case, when a nation is too mutch corrupted, neighbouring nations have a right to interfere by declaring war, to end corruption. Covetousness of land is very destructive in nature and causes mutch damage. Wars can be ended by duels(civilians cannot fight in a duel), agreements, at other time enough damage has been made or the objective as been reached. Some times both side are on the wrong path and need to be corrected. ( learn to handle the s"word" and your strengnt, "power" will be increased). Courage is a virtue it can be increased or lost.
