Colin Powell, who served Democratic and Republican presidents in war and peace, but whose sterling reputation was forever stained when he went before the U.N. and made faulty claims to justify the U.S. war in Iraq, has died of COVID-19 complications. He was 84. A veteran of the Vietnam War, Powell rose to the rank of four-star general and in 1989 became the first Black chairman of the Joint Chiefs of Staff. In that role, he oversaw the U.S. invasion of Panama and later the U.S. invasion of Kuwait to oust the Iraqi army in 1991.
