It is also a myth that military personnel and veterans love war. Those who have experienced war and its horrific effects firsthand rarely want more of it.
Then who are the ones clamoring for more war? They are inevitably those who are profiting from it and aren't fighting it. Some people call them warhawks. I call them chickenhawks. Chickenhawk is a much better description since they are comfortable with sending other people's children to die for political gain. They are often the same people who talk a lot about family values. They are failures in diplomacy and strategy.
The only place you will ever find glory in war is in a work of fiction. And it is fiction that politicians and their ilk sell the idea of war. Don't believe it! I understand war. Having been born in Vietnam, I've been affected by it. Having been a student of Sun Tzu, I know better ways to resolve conflict other than more killing and destruction.
If you have to read a novel about war, read All Quiet on the Western Front by Erich Maria Remarque. His book was banned and burned by the Nazis. Since Remarque had fought and been wounded in World War I, his novel is more non-fiction than fiction.
In short, war is extreme cruelty promoted by ignorance, lies, profit. The outdated and immoral act of incompetent old men sending young people to kill and die must end. To believe war is the answer to our problems is like believing in unicorns because Bigfoot told you that unicorns are real.
