What is the experience of black Americans traveling to Africa?

I will be glad that I was born in America. But tell a joke: an African country is in turmoil, and the United Nations has sent an American peacekeeping force. Two American soldiers are on sentry duty. The black soldier said to the white soldier next to him, I think you ran away. The white soldier said why? The black soldier said, if a mob comes at me, I will jump on you and shout, I caught one.
