[D]eveloped states have been more willing to appeal to moral values and to use such appeals in justification of initiatives—such as the NATO bombing of Yugoslavia—that would have been unthinkable during the Cold War. But these appeals only heighten the puzzle. If it makes sense to spend billions to endanger thousands of lives in order to rescue a million people from Serb oppression, would it not make more sense to spend similar sums, without endangering any lives, on leading many millions out of life-threatening poverty?
