Wars are started by a person or persons and are usually a quest for power for a person or a group of people and they don't really care how many people are killed nor how many families are losing a father, mother or brothers or whole families and their relatives. Sometimes, it is necessary to start a war by a peaceful nation against countries tat are harming and have the publically displayed their intentions to extend their borders by taking land from established country's land and people. This I would consider declaring a war to be the only necessary solution to the problem----but still a war with people getting maimed and killed. In World War One---Germany was the problem----once again lust for power. I wasn't even thought of at that period of time----in fact, I hadn't even arrived on the scene at that point of time. But, think about it for a moment-----there's not one inch of land that has increased in size in those thousands of years of civilization and wars. I was a training in Camp Blanding in Florida---we could look in any direction and there was a sign posted in large letters------"Kill or Be Killed"----"Kill or Be Killed". We were just 18 or 19 year old kids--------think about it--------"Kill or Be Killed"-what an education-but necessary to imprint it inside our young brains. It gave us young kids a reason to become killers-----hesitate for a second and you're dead. Back then in training, we used to repeat over and over was that wars were necessary to "Decrease The Surplus Population"--------It is most certainly a true statement.
