Let us face squarely the paradox that the world which goes to war is a world, usually genuinely desiring peace. War is the outcome, not mainly of evil intentions, but on the whole of good intentions which miscarry or are frustrated. It is made not usually by evil men knowing themselves to be wrong, but is the outcome of policies pursued by good men usually passionately convinced that they are right.
