Toward the end of WWII, Russian Army raped just about every woman in Germany. I’ve never had a problem with that. The wholesale rape was not a military measure by any standard; it didn’t serve to crush the German will to fight which was already at the low point by then. The rape was not an expression of Russian barbarity: female populations of Soviet-occupied Eastern Europe were largely spared. The rape was an act of vengeance, and I wholeheartedly approve of vengeance.

Societies punish criminals vengefully. In terms of prevention, it would suffice to ban, say, corruptioners from their jobs, but societies sentence them to prison. Relatives of the victims of violence long for revenge rather than mere prevention. Hebrews were commanded to exterminate Amalekites for the offenses of their ancestors. Vengeance is not nice, but it restores righteousness.

Defenders of the US nuclear attack on Japan bring up the necessity of crushing Japan’s will to fight to the last man. Nuking Hiroshima and Nagasaki didn’t achieve that end. After the first town was annihilated in nuclear attack, Japan did not react at all. The losses were actually much smaller than in Tokyo’s fire-bombing, and consisted largely of civilians – not a matter of the imperial army’s concern. Still, the US dropped the second nuclear bomb. The role of nukes in the capitulation is still a matter of historical debate in Japan, but most historians agree that exhaustion and the American promise of retaining the monarchy were the critical factors behind capitulation. Nuclear attacks on Japanese cities were a viable, but unnecessary military action. They were a legitimate act of revenge. Such was also the fire-bombing of Dresden – the answer to German attacks on Coventry.

Without vengeance, wars would become a limited liability affair. Aggressor can torture the victim’s civilian population, but the victim – once it gains the upper hand – ostensibly shouldn’t reciprocate. Such an arrangement, if ever implemented, would provoke the aggressors’ brutality: in the best case, they quash the resistance, while in the worst case, their civilians still won’t be harmed.

Fortunately, vengeance prevails in wars.
