Atrocities such as mentioned are highly to be condemned, no matter who the perpetrators are; but in itself, the U-boat warfare was an allowable means of defence.
The blockade is now admitted to be a permissible and necessary proceeding; the unrestricted U-boat warfare is stigmatised as a crime against international law. That is the sentence passed by might but not by right. In days to come history will judge otherwise.
