There are others. The trouble in Sudan is a blot crying out to Heaven.
I have no words for the horror that is Sudan. Many of us tried 4, 5 years ago to get the word out on what was happening. Even during Clinton. No one wanted to hear it. Millions of innocents lost in that time. I pray someone will step up to save the few left. No one in power sees this as a priority or they wish to appease...someone.
