Iran is in the throes of one of its most ferocious crackdowns on dissent in years, with the government focusing on labor leaders, universities, the press, women’s rights advocates, a former nuclear negotiator and Iranian-Americans, three of whom have been in prison for more than six weeks.

The shift is occurring against the backdrop of an economy so stressed that although Iran is the world’s second-largest oil exporter, it is on the verge of rationing gasoline. At the same time, the nuclear standoff with the West threatens to bring new sanctions.

The hardline administration of President Mahmoud Ahmadinejad, analysts say, faces rising pressure for failing to deliver on promises of greater prosperity from soaring oil revenue. It has been using American support for a change in government as well as a possible military attack as a pretext to hound his opposition and its sympathizers.

Some analysts describe it as a “cultural revolution,” an attempt to roll back the clock to the time of the 1979 revolution, when the newly formed Islamic Republic combined religious zeal and anti-imperialist rhetoric to try to assert itself as a regional leader.

Equally noteworthy is how little has been permitted to be discussed in the Iranian news media. Instead, attention has been strategically focused on Ahmadinejad’s political enemies, like the former president, Mohammad Khatami, and the controversy over whether he violated Islamic morals by deliberately shaking hands with an unfamiliar woman after he gave a speech in Rome.

Khatami, the lost hope of Iran’s reform movement, felt compelled to rebut the accusation because such a handshake is religiously suspect, but contended that the crowd seeking to congratulate him for his speech was so tumultuous that he could not distinguish between the hands of men and women.
