Passage: However, actual research shows that democracies are more likely to win wars than non-democracies. One explanation attributes this primarily to "the transparency of the polities, and the stability of their preferences, once determined, democracies are better able to cooperate with their partners in the conduct of wars". Other research attributes this to superior mobilisation of resources or selection of wars that the democratic states have a high chance of winning.Stam and Reiter also note that the emphasis on individuality within democratic societies means that their soldiers fight with greater initiative and superior leadership. Officers in dictatorships are often selected for political loyalty rather than military ability. They may be exclusively selected from a small class or religious/ethnic group that support the regime. The leaders in nondemocracies may respond violently to any perceived criticisms or disobedience. This may make the soldiers and officers afraid to raise any objections or do anything without explicit authorisation. The lack of initiative may be particularly detrimental in modern warfare. Enemy soldiers may more easily surrender to democracies since they can expect comparatively good treatment. In contrast, Nazi Germany killed almost 2/3 of the captured Soviet soldiers and 38% of the American soldiers captured by North Korea in the Korean War were killed.
