Almost as long as there has been life, war has been a part of it. Mankind continues to wage war even though the consequences often breed nothing but misery. However, when a person is called to defend his or her country, or protect other defenseless people, it is his duty to fight. There is no question that there is evil in the world and we must not rest on our laurels and say it is none of our business. We cannot stand by and watch while others are being persecuted. It is the duty of mankind to uphold justice.
