Gen. Romeo Dallaire was commander of the U.N. peacekeeping forces in Rwanda 10 years ago during one of the worst massacres in modern history. Some 800,000 Rwandans were killed in 100 days. Most of them were Tutsi and moderate Hutu civilians. During that time Dallaire and his troops were denied authority to intervene. The experience changed him, tormented him, and filled him with guilt. He suffered from post traumatic stress syndrome, was suicidal and depressed. He's written a new account, Shake Hands with the Devil: The Failure of Humanity in Rwanda.

His new book, Moyers on America (The New Press) is a first-ever collection of his essays and speeches. Moyers is the host of Now with Bill Moyers on PBS. He was one of the organizers of the Peace Corps, spokesperson for President Lyndon Johnson, a senior correspondent for CBS News, and producer of many public TV series. Moyers has won 30 Emmy Awards.

Wilson is a former career diplomat, serving from 1976 to 1998. He had diplomatic posts throughout Africa and was ambassador to Gabon. Wilson was the acting ambassador to Baghdad when Iraq invaded Kuwait in 1990. President George W. Bush, in his 2003 State of the Union address, stated that "Saddam Hussein recently sought significant quantities of uranium from Africa." But in February 2002 Wilson investigated reports of Iraq's attempt to buy uranium from Niger, and found no evidence of such an attempt.
