No, not at all. Usually, those are humans.
Just understand it, that you are talking about a different exotic culture. We have no problems with nudity. But can't think positive of war - after all, we barely managed to patch up all the damages of the last one here.
The problem is that wars aren't fought by mutual agreement between the two sides. You only need one aggressor to start a war. If you take too dim a view of war, the wars you get involved in will be short and will tend not to be resolved in your favor. If you take too rosy a view of war, you'll be the aggressor far too often and involve yourself in too many wars that you don't need to fight, and eventually your neighbors will decide that if you aren't cut down to size the wars won't stop.
Europe, at present, is in danger of falling into the first trap, and the USA, largely the second. The tricky part is, while it's easy to spot general trends in this regard in a society's behavior, figuring out the right course of action for a given potential conflict is much trickier.
A large part of the reason for the US's present attitude towards war is that in WWII, the US managed to win, rather than just losing less than the other guy, as is the typical case for the victor in a war. This isn't so much an indicator of US fighting prowess as just an accident of the geopolitical and economic context of the war: the US had the economy to fund its side in the war, while its homeland remained isolated by thousands of miles of ocean from the actual fighting, and so, in the end, of the major world economies, the US alone emerged with an intact industrial base, and, meanwhile, everyone owed it money. Combined with Hitler's obvious insanity, this gave us too rosy a view of war; when you go to war, you stop evil men in their tracks and benefit greatly from it.
