DEUT991 When fighting a war that God commanded to fight, even to conquer a nation, the Torah [this verse] commands that the Jewish people must first ask for and offer peace prior to attack. If the nation agrees to peace under Jewish rule, it is forbidden to fight war against such a nation. Maimonides (Hilchot Melachim 6:1) codifies this law and explains its details. The Jewish nation cannot make a war unless it first offers peace. If the nation accepts the seven Noahide laws and agrees to pay taxes to the Jewish nation, then the Jewish army may not attack. After making a treaty of peace with any country, even if the other nation is suspected of wrongdoing or it would be advantageous for the Jews to break the treaty, it is forbidden to renege on such an agreement (Maimonides, Hilchot Melachim 6:3). Therefore, we see that in Judaism, unlike in most societies in a war situation, Jewish values may not be abandoned, and they must help to guide the process of conducting war.
