The US foreign policy regarding Iran is foolish.  Noam Chomsky analyzes the situation:

 

“The most dangerous immediate foreign policy crisis is the conflict with Iran, which has been deemed the official source of all evil. Iran must end its “aggression” and become a “normal country” — like Saudi Arabia, which is making rapid progress in Trump’s fantasy world, even “a great job in Saudi Arabia from the standpoint of women,” he explained at G20.

The charges against Iran resonate through the media echo chamber with little effort to assess the validity of the accusations — which hardly withstand analysis. Whatever one thinks of Iranian international behavior, by the miserable standards of U.S. allies in the region — not to speak of the U.S. itself — it is not much of a competitor in the rogue state derby.

In the real world, the U.S. unilaterally decided to destroy the well-functioning nuclear agreement (JCPOA), with ludicrous charges accepted by virtually no one with the slightest credibility, and to impose extremely harsh sanctions designed to punish the Iranian people and undermine the economy. The [U.S. government] also uses its enormous economic power, including virtual control of the international financial system, to compel others to obey Washington’s dictates. None of this has even minimal legitimacy; the same is true of Cuba and other cases. The world may protest — last November, the UN General Assembly once again condemned the U.S. embargo on Cuba, 189-2 (only the U.S. and Israel voted against the resolution). But in vain. The weird idea of the founders that one might have “decent respect to the opinions of mankind” has long vanished, and the pained bleatings of the world pass in silence. On Iran as well.

This is not the place to pursue the matter, but there is a good deal more to say about the U.S. specialty of resorting to sanctions (with extraterritorial reach) to punish populations — a form of “American exceptionalism” that finds its place within what Nick Turse calls “the American system of suffering” in his harrowing expose of the U.S. assault on the civilian population of South Vietnam. The right to engage in this malicious practice is accepted as normal in the U.S. doctrinal system, with little effort to analyze the actual motives in individual cases, the legitimacy of such policies, or in fact even their legality. Matters of no slight significance.

With regard to Iran, within the government-media doctrinal system, the only question that arises is whether the victim will respond in some way, maybe by “violating” the agreement that the U.S. has demolished, maybe by some other act. And if it does, it obviously will be deemed to deserve brutal punishment.

In commentary made by U.S. officials and media, Iran “violates” agreements. The U.S. merely “withdraws” from them. The stance is reminiscent of a comment by the great anarchist writer and Wobbly activist T-Bone Slim: “Only the poor break laws — the rich evade them.”
