There is a difference between Thou Shalt Not Kill and Thou Shalt Protect. Mercenaries would be interesting and effective since they would not care about diplomacy or outcomes except achieving the goal they are paid to achieve which would be to protect the civilians in Darfur.

Of course it would be cheaper and more "ethical" to just fake discover of a massive oil reserve in the region. Then every industrialized nation on the planet would be falling all over themselves to bomb the holy hell out of the Sudanese and anyone else causing problems with the oil supply.

Don't call me unless you have a real problem, you know like the meltdown on Wall Street, the US housing crisis or if Iran ever gets nukes.
