Of course some wars may have been necessary or inevitable, but none was ever regarded as holy. For us, a holy war is a contradiction in terms. War dehumanizes, war diminishes, war debases all those who wage it. The Talmud says, "Talmidei hukhamim marbin shalom baolam" (It is the wise men who will bring about peace). Perhaps, because wise men remember best.
