War is deviltry. It calls for sacrifices indeed, but not at the altar of love. “Greater love hath no man than this.” A great blasphemy this, to use Christ’s words in connection with men going to war. They go because they are drafted, because they are afraid of what their neighbors will say, because the pay is good, because the benefits accruing afterward (the G.I. Bill of Rights) are great. And they are told by the press and the pulpit that they are going because they love their fellows, and they are filled with a warm glow of self-love. And then they are given their intensive training in how to escape death, how to kill. Greater love hath no man than this, that he lay down his life for his brothers, and the Russians are our brothers, the Negro is our brother, the Japanese are our brothers, the Germans, the Mexicans, the Filipinos, the Jews, the Arabs.
. . .
So let’s not have any more talk about God and country. The battle is for this world, for the possessions of this world.
