An anti-war mental exercise
If you are terrified by the prospect of your mental exercise becoming reality, then you should also be terrified of wars because this is what wars do to people you love. So, whenever you get carried away by thinking about the strength and glory of "our" army, bring back the image of the disfigured body of the person you love. This is what armies do--they kill people you, or other people, love. If you say--yes, but we do it in self-defense, you are implying that it is justified to kill someone's child. If you say--yes, but we had no other way of defending ourselves, you are still saying that it is justified to kill someone's child. Now, imagine I say that to you--sorry, but I had no choice but to kill your child (or someone else you love). What would your response be?
