Leader of Mali military coup trained in United States
This is from last March. I have read elsewhere that not only have some U.S.-trained officers defected, but they took the U.S.-provided weapons with them.

The leader of a military coup in the West African country of Mali received military training in the United States on several occasions, a U.S. defense official said Friday.
Capt. Amadou Haya Sanogo, who led a renegade military faction that on Thursday deposed Malis democratically elected president, visited the United States several times to receive professional military education, including basic officer training, said Patrick Barnes, a U.S. Africa Command official based in Washington.
Barnes said he could not immediately provide further details about the duration or nature of Sanogos participation in the International Military Education and Training program. The State Department funds that program, and foreign officers are generally selected by U.S. Embassy officials.
