This summer marks the fifteenth anniversary of the Srebrenica massacre, where 8,000 Muslims, mostly men and boys, lost their lives in the single worst act of genocide in Europe since the 1940s. For many, the key lesson of Srebrenica is that the United States should have used military force against the Serbs sooner than they did. For others, Srebrenica is a painful reminder of the overstated value of military intervention as a solution to a humanitarian crisis which in reality, could have been avoided through diplomatic means.
