We really thought that war was good?

How dumb were we in the past to have actually thought that there could be anything good about war? War is war! War is evil! War cannot ever be called anything other than vomit! It you like shooting at people who get in your way, merely because they have gotten in your way, then you are crazy! Yet, this is what war demands! Yes, it is better than slavery, but that doesn't make it good!
