So you think that war cannot be defensive? Rather narrow a viewpoint, there, Miguel. :o)
But I'm not one to play semantic games. Yes, the purpose of a military is to wage war, be it defensive or not. We also get other tasks on occasion, though. Peacekeeping, humanitarian missions, operations short of war, etc. I'm not a pacifist, obviously. (Though my Hippocratic oath does place some limits on me. I can discuss the Geneva Conventions regarding medical personnel, if you like.)
But, wow, we're going to get into another holy war, here, aren't we...? :o)
EDIT-- So, you edited that one under me, eh, Miguel? Are you calling me names? Well, at least you have the balls to do it in public. I'll give you that. I do take offense to being called a warmonger. My opinions about appropriate uses for the military might surprise you. If I'm misinterpreting that comment, I recommend you clarify it right quick or the holy war is about to start.
P.S.- My apologies in advance, Jim. I hope that I amswered your question. With more and more joint operations nowadays they just needed a word that covered everybody.
