From TomDispatch, here's Noam Chomsky, very aptly putting the whole US "should we go to war with Iran" line in context.
This "debate" is a typical illustration of a primary principle of sophisticated propaganda. In crude and brutal societies, the Party Line is publicly proclaimed and must be obeyed -- or else. What you actually believe is your own business and of far less concern. In societies where the state has lost the capacity to control by force, the Party Line is simply presupposed; then, vigorous debate is encouraged within the limits imposed by unstated doctrinal orthodoxy. The cruder of the two systems leads, naturally enough, to disbelief; the sophisticated variant gives an impression of openness and freedom, and so far more effectively serves to instill the Party Line. It becomes beyond question, beyond thought itself, like the air we breathe.
The debate over Iranian interference in Iraq proceeds without ridicule on the assumption that the United States owns the world. We did not, for example, engage in a similar debate in the 1980s about whether the U.S. was interfering in Soviet-occupied Afghanistan, and I doubt that Pravda, probably recognizing the absurdity of the situation, sank to outrage about that fact (which American officials and our media, in any case, made no effort to conceal). Perhaps the official Nazi press also featured solemn debates about whether the Allies were interfering in sovereign Vichy France, though if so, sane people would then have collapsed in ridicule.
In this case, however, even ridicule -- notably absent -- would not suffice, because the charges against Iran are part of a drumbeat of pronouncements meant to mobilize support for escalation in Iraq and for an attack on Iran, the "source of the problem." The world is aghast at the possibility. Even in neighboring Sunni states, no friends of Iran, majorities, when asked, favor a nuclear-armed Iran over any military action against that country. From what limited information we have, it appears that significant parts of the U.S. military and intelligence communities are opposed to such an attack, along with almost the entire world, even more so than when the Bush administration and Tony Blair's Britain invaded Iraq, defying enormous popular opposition worldwide.
He also places the issue of a nuclear armed Iran in context, and puts the hypothetical Iranian shoe on the American foot.
Doubtless Iran's government merits harsh condemnation, including for its recent actions that have inflamed the crisis. It is, however, useful to ask how we would act if Iran had invaded and occupied Canada and Mexico and was arresting U.S. government representatives there on the grounds that they were resisting the Iranian occupation (called "liberation," of course). Imagine as well that Iran was deploying massive naval forces in the Caribbean and issuing credible threats to launch a wave of attacks against a vast range of sites -- nuclear and otherwise -- in the United States, if the U.S. government did not immediately terminate all its nuclear energy programs (and, naturally, dismantle all its nuclear weapons). Suppose that all of this happened after Iran had overthrown the government of the U.S. and installed a vicious tyrant (as the US did to Iran in 1953), then later supported a Russian invasion of the U.S. that killed millions of people (just as the U.S. supported Saddam Hussein's invasion of Iran in 1980, killing hundreds of thousands of Iranians, a figure comparable to millions of Americans). Would we watch quietly?
It is easy to understand an observation by one of Israel's leading military historians, Martin van Creveld. After the U.S. invaded Iraq, knowing it to be defenseless, he noted, "Had the Iranians not tried to build nuclear weapons, they would be crazy."
Surely no sane person wants Iran (or any nation) to develop nuclear weapons. A reasonable resolution of the present crisis would permit Iran to develop nuclear energy, in accord with its rights under the Non-Proliferation Treaty, but not nuclear weapons. Is that outcome feasible? It would be, given one condition: that the U.S. and Iran were functioning democratic societies in which public opinion had a significant impact on public policy.
As it happens, this solution has overwhelming support among Iranians and Americans, who generally are in agreement on nuclear issues. The Iranian-American consensus includes the complete elimination of nuclear weapons everywhere (82% of Americans); if that cannot yet be achieved because of elite opposition, then at least a "nuclear-weapons-free zone in the Middle East that would include both Islamic countries and Israel" (71% of Americans). Seventy-five percent of Americans prefer building better relations with Iran to threats of force. In brief, if public opinion were to have a significant influence on state policy in the U.S. and Iran, resolution of the crisis might be at hand, along with much more far-reaching solutions to the global nuclear conundrum.
