Food is a weapon - a very effective weapon. People don't cultivate, don't farm, you cut the road off, then you subjugate them very easily.

Probably 99 percent of Nuba are subsistence farmers. They have maybe two or three cattle, a few goats. Now there are food shortages, so they're very thin. But traditionally, they are very strong and muscular. They grow sorghum, okra, a bit of corn, some peanuts. If they need money, they'll sell one of their animals or sell some sorghum.

I was with a Navy F-18 squadron, and I know a single squadron could finish off the entire Sudanese air force in a day.

My parents have been married 50-some years, and I've never heard them fight. I got the chance to attend great universities and medical school.

The Sudanese army has retaken some towns. The people there are all living in caves because the Sudanese army is shelling their villages.

Humor can be an incredible, lacerating and effective weapon.
