ICC Prosecutor Luis Moreno-Ocampo has asked the court to issue an arrest warrant for President Omar Hassan al-Bashir, but a decision on this might not be made for some months.
Sudan is not a party to the ICC, and al-Bashir has said he's going to ignore it.
The UN Security Council has Libya holding it hostage on behalf of the Arab League and China hungry for any source of oil it can find, primary for fueling its economic boom and secondarily for driving up commodity prices to slow down rival Western economies, so don't expect anything out of them any time soon.
Darfurese will continue suffer and die by the thousands.
