This resolution:

See "The United States Holocaust Memorial Museum :  Smallest Witnesses".  Children drew scenes of devastation: pictures of their villages being attacked by “Janjaweed,” bombings by Sudanese government forces, the shootings, the rapes, the burning of entire villages, and the flight to Chad. The children, from seven refugee camps, insisted the drawings be shared with the rest of the world.
