Genocide: Always Again?

Centerfield, a moderate blog, argues that smallish, quasi-confrontational peacekeeping forces appear not to work to prevent genocide but allow the world to get complacent and feel that serious action is being taken when little is actually being done: "In practice, there must be a trusted democracy at the head of the coalition, willing to contribute most of the resources to end the genocide. And it must be a country that actually cares alot about genocide. And it must be big enough that its military contribution alone is a substantial fraction of what's needed to beat the bad guys' army." It wonders if it's reasonable to try to fulfill a "never again" pledge, if a reformed and more democratic U.N. would help in this arena, and how to prioritize actions if the world can't stop some genocides.
