nalod,
firstly, it is a grand mistake to assume u.s. government interests are altruistic in nature, which is what the tone of your position sounds like it's taking on.
the support of the shah, and the too long a list of authoritarian and totalitarian rulers/regimes that have been propped up for more than a century, or lack of willingness to stand for the so-called values this nation stands for...going back to the haitian revolution, which the u.s. turned their back on, to the surprise of haitians.
these decisions are typically about positioning the u.s. to be winner in the global game of chess...whether it be economically or militarily.
which means human rights and equality come second to these so-called "interests."
and is typical of a world still stuck in nation-state mentality, us vs. them, me first, then you...
your entire pov, imho, and some of the other comments in this thread come across as seeped in such thinking, and leads to the kinds of so-called rationalizations for accepting atrocities as "part of what happens," and is of course mostly coming from people living in privileged situations where these issues have zero impact on folks' day to day life. It also speaks to the level of arrogance and paternalistic attitudes that exists in too many westerners thinking (more so in the u.s. today, i believe) as if we are the only one's who understand how to create a good society.
in iran, it is well known that there were leaders and many citizens who WERE PRO-DEMOCRACY who were not only not supported, but undermined by the CIA. Why? Most likely because u.s. businesses couldn't dominate the marketplace and take advantage of cheap oil provided by the shah. this is similar to what happened in in zaire, chile, and some south american countries where democratically elected leaders, who were not going to let the big u.s. biz control their markets...which has led to a large amount of evidence to suggest the u.s. government, as a result of these leaders refusal to bow down, for the CIA to assist or directly arrange the assassination of these leaders.
with east timor, little known to most americans, the u.s. government in the 1970's (Ford/Kissinger), blatantly supported indonesia's invasion of it (selling weaponry used for the invasion), which lead to amongst the worst atrocities of the 20th century, leaving 300,000 people dead, with blood on the u.s. government's hands.
so, i am sorry to say, much of this so-called debate you are having here, is total misdirection, and really does not get to the root of the problem.
Forum Po Po and #33 for a reason...
