The parallel example for Syria is not Iraq, Afghanistan or Libya -- it's Bosnia. Like the Syrian conflict today, Bosnia saw horrific atrocities, unprecedented numbers of refugees and an exorbitant death toll. Like Syria, the crisis in the Balkans was thought unsolvable and intractable. Bosnia's strongest allies worried that action to protect civilians could escalate the conflict regionally and even globally.
We must never forget the genocide in Srebrenica. We must always honor its victims, its survivors. But we must never forget also that our words will ring hollow if, in the here and now, we don't believe the unbelievable, if we don't end the culture of impunity that exists in so many places around the world, and if we don't strengthen our resolve to protect those who count on us all.
Every year we commemorate the genocide, we expect that those who betrayed Srebrenica might this time ask for forgiveness from the survivors. Instead, much of Europe appears inclined to forget Srebrenica and punish all Bosnian & Herzegovinians ("BiH") for reminding it of its collective failure to prevent the genocide.
