Let's examine just a few of the events that occurred under various U.S. Secretaries of State in the period since the World War 2. John Foster Dulles, who had the unique situation that his brother, Allen, was the head of the CIA, exercised the freest hand of any Sec of State in the modern era. He played a major role in the Coups in Iran in 1953 and Guatemala in 1954, the various attacks on Cuba after Castro came to power, the first attempt at a coup in Indonesia in 1958 (later successful in 1965), and of course the early lead up to the largest single U.S. crime the War in Vietnam. Good Presbyterians, the two of them took good care of their previous corporate clients at the law firm of Sullivan and Cromwell in New York. The ramifications of some of their actions are still with us to this day. The most prominent being the Islamic Republic of Iran, a regime that might never have occurred had the conservative nationalist Mohammed Mosaddegh not been deposed.
Good old boy Dean Rusk was the Sec of State when the Brazilian president Joao Goulart was deposed in a military Coup d'etat that saw considerable maneuvering by the CIA. The military government that took power after the coup was notorious for their heavy handed repression. Eventually Goulart died of a heart attack in 1976 that many see as suspicious, the previous president Juscelino Kubitschek de Oliveira, another nationalist reformer died in a suspicious car crash, also in 1976 (both when Kisssinger was Sec of State). The CIA often operates (as do many intelligence agencies from various countries) out of the embassy under diplomatic "cover"; thus the Sec of State is ultimately responsible for what is done by these CIA agents. The final successful coup against Sukharno of Indonesia took place under Rusk, here the final death toll was in the area of 1 million killed in the slaughters that followed his deposal.
Kissinger further sullied his tenure with numerous Vietnam and other SE Asian hardline actions. He was a hardline counsel to Nixon to stay the course in Vietnam and attempt to get the most "favorable" settlement possible; always at the expense of the long-suffering people of SE Asia in terms of more bombing raids or various military offensives. Not to be forgotten is, of course, the overthrow of Salvador Allende in Chile in 1973 (interestingly this occurred on Sept. 11, 1973, the first 9-11 outrage) with a killing of socialists and other supporters of the elected Allende regime that, in the end, numbered around 50,000. Special sadism was shown in the killings of Victor Jara and Pablo Neruda cultural figures in Chile supportive of the Allende government.
Finally the cases of Iraq and Afghanistan deserve mention. Iraq was bombed in a series of campaigns that intentionally destroyed the nation's infrastructure that supplied safe drinking water, health care, and electricity. This policy led directly, and quite predictably, to the deaths of about 1 million people mostly children, the elderly, and the poor; this particular outrage only intensifies the repugnace of Madeleine Albright's famous comment that the deaths were "worth it". This was first degree murder of over a million people; certainly a first rank war crime for which Bush Sr., James Baker, Lawrence Eagleburger, Bill Clinton and Warren Cristopher (in addition to Albright) at the least should be answering for crimes against humanity at the World Criminal Court in the Hague. Afghanistan, after 45 years of independence and minimal great power intrigue from 1927 - 1972, was developing as a moderate Islamic state with high levels of education and professional development among at least the more prosperous urban women when it fell afoul of great power intrigue between the USSR and the U.S. Here Zbiegniew Brezinski (Carter's National Security advisor), a Polish nobleman, with a deep abiding hatred for all things Russian, saw a chance to make trouble for the Soviets. He planned to bait them into their own "Vietnam" and still considers it a great triumph, Warren Christopher was the Sec of State then. These early outrages were then followed by the Bush Jr. era attacks where Collin Powell and Condaleeza Rice take up their assigned roles.
So it goes on, whether white males, Jews, African Americans, male or female the drum beat of murder and mayhem, facilitated by the venerable leaders of the diplomatic corps, in the service of U.S. imperialism keeps occurring. Not that the U.S. is out of step with the rotten record of the other great powers, but the holier than thou attitude, the shining city on a hill tripe is what is most ridiculous.
