How to proceed with the arrest warrant?

Either make a deal.
1. Start secret communications with leading regime insiders and Salva Kiir and Riek Machar to make a deal. Salah Gosh flew to Washington in a CIA plane, for goodness sake. It can be done.

2. The deal can be that the arrest warrant is quashed- the Security Council can do whatever it pleases- in return Darfur is turned into a trustee type zone under UNAMID supervision, with elections along with national elections, free and fair, on January 9 2010. Al-Bashir goes to Doha for 5 years. A Truth Commission is established, and general amnesty issued for those who come forward to confess full nature of their crimes.

3. A $1 billion trust fund is set up to enable restitution and resettlement.

Or start some crafty planning to arrest al-Bashir.

2. The deal can be that arrest warrant is executed by regime insiders in return for immunity. Security Council issues sealed instructions to ICC prosecutor to not pursue other cases in Sudan. Al-Bashir goes to Dock for 5 years as trial drags on. All other crimes left to the dustbin of history, as in the North-South war of 1983-2005.

3. A $.001 billion trust fund is set up to enable comfortable retirement for regime insiders.

Skeptics? Let's go down the list. Mobutu, Idi Amin, Fujimori, Mengistu, Pinochet, Nixon, Nimeiri, Cedras (where is he, anyway), Duvalier, etc.
