Did not. The only genocide in Bosnia was the destruction of Serbian Kraina by NATO/Croat/Muslim troops. See the ethnic map of Bosnia before the war and now to verify where the REAL genocide took place. The rest is the trick of a thief crying "Stop Thief".
There was enough death on both sides of the Drina to make everyone in the region accountable, it was a tri-fecta of blame. A good portion of that blame can be pinned squarely on the shoulders of the outside powers, under dubious pretenses, who felt it that this was more of an opportunity to exert influence rather than help solve the problem, the US included.
