Tehran’s proxies have been ramping up their activities on the battlefields of the Middle East in recent weeks. In Iraq, Syria, and Yemen, forces loyal to the Iranian regime have been busy, escalating attacks against US and Saudi targets. One spark for this intensification may be the second anniversary of the assassination of Qassem Soleimani, the Iranian general who set in motion much of the chaos still ravaging the region. But some analysts believe the prime reason is the Iran-US nuclear talks that have resumed in Vienna. As the talks progress, albeit painstakingly, Iran’s officials have been increasingly upbeat, believing it is on the verge of salvaging a deal that would ease crippling US sanctions on its financial institutions and political bodies. An informed source has told Arab News that the nuts and bolts of a new arrangement between Washington and Tehran are now primarily in place. One remaining obstacle is a demand by Iran that the next US president should not walk out of any new deal. Whether the US could honor such a pledge remains unclear. In 2018, US President Donald Trump scorned and abandoned the “one-sided deal.” Iran responded by ceasing its cooperation with international inspectors that kept tabs on its nuclear infrastructure and ramping up its enrichment efforts. The current president, Joe Biden, has staked much of his first term foreign policy legacy on reinstating the deal, formally known as the Joint Comprehensive Plan of Action with Iran. This has earned the opprobrium of regional allies as his officials persist with talks with Iranian hardliners. Entifadh Qanbar, a former Iraqi spokesperson, said: “Iranians like to twist arms in negotiations. Robert Malley seems to be trying hard to appease the Iranians and, unfortunately, has the upper hand in the Biden administration when it comes to the negotiations. The Biden administration is coming off weak, especially in light of the chaos in Afghanistan after the US withdrawal.” Dr. Ras Zimmt, an expert on Iran at the Institute for National Security Studies in Israel, said: “Looking at the recent attacks on Syria and Iraq, one of the main reasons it happened, I believe, is the second anniversary of the killing of Qassem Soleimani.” He said this hung a pall over the negotiations from the Iranian side. Washington’s response to the attacks on US forces has been a far cry from Trump’s reaction as Iran-backed rioters approached the US embassy in Baghdad two years ago, when he sanctioned the assassination of Soleimani. Iranian president Ebrahim Raisi spoke on the anniversary of Soleimani’s death at a ceremony in a large prayer hall in Tehran. The president vowed revenge on Donald Trump, calling him the primary “aggressor and assassin.” The Iranian general and his ally, Abu Mahdi al-Muhandis, who was also killed in the drone strike in January 2020, had been masters of the art of wielding powerful proxy forces in Iraq, Syria, Lebanon, and Yemen and also of bombing the US into concessions with low intensity – but high political impact – rocket fire. On Wednesday, an armed pro-Iranian militia called Gassem Al-Jabarayn claimed responsibility for Iraq’s drone and rocket attacks, which caused no casualties. The group posted online that they vow to maintain their attacks until there was a complete US withdrawal from Iraq. This group is believed to be a cover for one of the main Iranian proxies, whose influence in Iraq remains extensive as the central government continues to struggle to assert control.
