In a bitter irony, Colin Powell, who was responsible for the coverup of the My Lai massacre acceded to a "brilliant" career in the Armed Forces. In 2001 he was appointed Secretary of State in the Bush administration. Although never indicted, Powell was also deeply implicated in the Iran-Contra affair.
It is worth noting that Colin Powell was Chairman of the Joint Chiefs of Staff at the time of the Gulf War, which resulted in the deaths of thousands of retreating Iraqi soldiers in what British war correspondent Felicity Arbuthnot entitled "Operation Desert Slaughter".
