Gen. Ratko Mladic, the world's most wanted war crimes suspect, was arrested last week in Serbia. His detention, while delayed, is a victory for justice nonetheless. It is a powerful reminder to those who would contemplate similar crimes that they will know no rest; they will have to live their lives in fear of being hunted down and held accountable for their acts — as they should.

Gen. Mladic led Bosnian Serb military forces during the breakup of the former Yugoslavia in the 1990s. His moment of greatest infamy came during the 43-month siege of Sarajevo, a former host of the Olympics and a city that had been celebrated for its cultural diversity.

Looking down from the hills from which his forces surrounded the city, he told his troops simply to "burn it."
