Einstein

"He who joyfully marches to music in rank and file has already
earned my contempt. He has been given a large brain by mistake,
since for him the spinal cord would fully suffice. This disgrace to
civilization should be done away with at once. Heroism at command,
senseless brutality, deplorable love-of-country stance, how
violently I hate all this, how despicable and ignoble war is; I
would rather be torn to shreds than be a part of so base an action!
It is my conviction that killing under the cloak of war is nothing
but an act of murder."
-Einstein
