Johnathan Morris- What is it good for?

War can be necessary to better mankind, although some innocent lives may be taken. I'm not saying all wars that have happened were necessary, but some, like the Revolutionary War or the Civil War were needed because there was no other solution that was moral. Without either of these wars slavery in America might still exist and/or we could be controlled by the British. These wars were fought for a reasonable cause, unlike others that were only fought because the two or more sides didn't like each other. Similar to the wars going on in the middle east. When there are terroristic threats to our country. I believe we should defend our citizens. Not like what we did to Japan, because that was unnecessary, but if violent actions are the only solution, then that's what should be done.
