'In the past year Iran has issued several warnings to the United States about the consequences of an American or Israeli attack. One statement, issued in November by a high Iranian military official, declared: "If America attacks Iran, its 200,000 troops and 33 bases in the region will be extremely vulnerable, and both American politicians and military commanders are aware of it." Iran apparently believes that American leaders would be so deeply distressed by the prospect of their young men and women being endangered and possibly killed that they would forswear any reckless attacks on Iran. As if American leaders have been deeply stabbed by pain about throwing youthful American bodies into the bottomless snakepit called Iraq, or were restrained by fear of retaliation or by moral qualms while feeding 58,000 young lives to the Vietnam beast. As if American leaders, like all world leaders, have ever had such concerns.
Let's have a short look at some modern American history, which may be instructive in this regard. A report of the US Congress in 1994 informed us that:
Approximately 60,000 military personnel were used as human subjects in the 1940s to test two chemical agents, mustard gas and lewisite
. Most of these subjects were not informed of the nature of the experiments and never received medical follow-up after their participation in the research. Additionally, some of these human subjects were threatened with imprisonment at Fort Leavenworth if they discussed these experiments with anyone, including their wives, parents, and family doctors. For decades, the Pentagon denied that the research had taken place, resulting in decades of suffering for many veterans who became ill after the secret testing.
In the decades between the 1940s and 1990s, we find a remarkable variety of government programs, either formally, or in effect, using soldiers as guinea pigs -- marched to nuclear explosion sites, with pilots sent through the mushroom clouds; subjected to chemical and biological weapons experiments; radiation experiments; behavior modification experiments that washed their brains with LSD; widespread exposure to the highly toxic dioxin of Agent Orange in Korea and Vietnam . . . the list goes on . . . literally millions of experimental subjects, seldom given a choice or adequate information, often with disastrous effects to their physical and/or mental health, rarely with proper medical care or even monitoring.'
