From the moment the first protesters hit Tahrir Square in Cairo, Iran's leadership has cracked down hard, instituting a brutal campaign of terror against its own people. The most gruesome manifestation of this repression has been a wave of public executions.
Since January, Iran has been on an execution binge. In February, the United Nations reported that the rate of executions in Iran had increased threefold over the year before. Amnesty International reported that Iran is the only country known to have executed juvenile offenders this year, a violation of international law. And though exact numbers are difficult to come by, human-rights organizations estimate that more than 140 people have been executed in Iran so far this year - a rate that, if continued, would push the number well past the 2010 total.
What is perhaps most disturbing, and provides clear evidence of Iran's effort to intimidate and terrorize its own population, is the growing number of executions taking place in public. Amnesty International estimates that as many as 13 people had been hanged in public this year by the end of April, compared with 14 in all of 2010. In a number of instances, those executed have been left hanging high in the air on construction cranes for all to see.
An Amnesty official noted in an April report: "It is deeply disturbing that despite a moratorium on public executions ordered in 2008, the Iranian authorities are once again seeking to intimidate people by such spectacles, which not only dehumanize the victim but brutalize those who witness it." Only a month later, Iran Human Rights reported that the regime put 54 people to death in May, with 15 of the executions carried out publicly.
The international community needs to call for an end to this kind of barbarism and highlight more broadly the deteriorating human-rights situation in Iran.
In response to Iran's brazen attempts to intimidate and terrorize its own people, United Against Nuclear Iran has launched the Cranes Campaign. The goal is to educate crane manufacturers worldwide about the Iranian regime's misuse of their products and how it can tarnish their brands. We know these companies - including Switzerland's Liebherr, China's XCMG, and Japan's Tadano and UNIC - do not in any way condone the use of their cranes to stage public executions. That's why they should take the principled stand of renouncing their business ties with the regime until Iran becomes a civilized member of the international community.
Already, some companies are doing just that. U.S. construction manufacturers Terex Corp. and Caterpillar, as well as Japan's Komatsu, have ended their business ties with Iran.
Severing business dealings sends an unequivocal message to leaders in Iran that the international community finds their activities abhorrent. But that is just a start. Governments from around the world need to scrutinize the worsening human-rights situation and call Iran to account.
It's no coincidence that Iran's increased staging of public executions came as protest movements were gaining steam throughout the Middle East. What better way to keep Iranians from having "dangerous ideas" like their neighbors'? And it should come as little surprise that Iran is now aiding other governments in the region, notably Syria, in their efforts to suppress domestic uprisings.
The lesson Iran learned from the uprisings of 2009 - and the one it is trying to impart to other leaders in the region - is that the way to quash peaceful dissent is through a public display of brute force, terror, intimidation, and humiliation. The response from the international community must be resolute and firm: Iran's behavior is unacceptable and far outside the boundaries of civilized society. Civilized nations, and the businesses based in them, should never be complicit.
