WASHINGTON/DUBAI (Reuters) - President Donald Trump said on Monday he would name Iran’s elite Islamic Revolutionary Guard Corps a terrorist organisation, in an unprecedented step that drew Iranian condemnation and raised concerns about retaliatory attacks on U.S. forces.
The action by Trump, who has taken a hard line towards Iran by withdrawing from the 2015 Iran nuclear deal and re-imposing broad economic sanctions, marks the first time the United States has formally labelled another nation’s military a terrorist group.
The U.S. step, which takes effect on April 15, prompted an immediate response from Iran, whose Supreme National Security Council in turn designated U.S. military forces as a “terrorist organisation,” Iranian state-run TV reported.
“The U.S. military bases and their military forces in the region will be considered terrorist bases and terrorist forces that will be dealt with and confronted accordingly,” Iran’s Deputy Foreign Minister Abbas Araqchi told Iranian state TV, calling the U.S. decision “a major strategic mistake.”
“The IRGC is the Iranian government’s primary means of directing and implementing its global terrorist campaign,” Trump said in a statement. His administration has long criticized Iran for its influence in Iraq, Syria and Yemen.
Critics of Trump’s decision said it was largely symbolic because U.S. law already carried penalties of up to 20 years in prison for U.S. persons who deal with the IRGC because of its designation under another U.S. sanctions programme, the U.S. Specially Designated Global Terrorist list.
Senior U.S. military commanders share Trump’s concerns about Iran and the IRGC but long opposed the designation due to concern over a potential backlash against U.S. forces in the Middle East and the problems it could create for U.S. partners who have a relationship with Iran, U.S. officials say.
The Pentagon declined to discuss what the U.S. military was doing to protect American troops from any retaliation by the IRGC or Iran-aligned militia in places like Iraq.
U.S. officials, speaking on condition of anonymity, said the designation did not mean the U.S. military would start treating the IRGC like al Qaeda, Islamic State or other militants that it can target at will.
“This is not about going to war with Iran or killing a bunch of Iranians. Absolutely not,” said one, adding the U.S. military had not been given any new direction to “go after” Iranian forces.
Three Iranian officials said that despite Tehran’s harsh rhetoric, Iran’s reaction will be “diplomatic and mild.”
Jason Blazakis, a former State Department official who oversaw the process for labelling foreign terrorist organizations, said he believed the IRGC designation was done for purely symbolic and domestic political reasons that could have deadly consequences for U.S. troops.
He said it could prompt Qassem Soleimani, the powerful commander of the Quds Force, the IRGC’s elite foreign espionage and paramilitary contingent, to allow IRGC-controlled Shi’ite Muslim militias to retaliate against U.S. forces in Iraq.
“I imagine that tight leash he (Soleimani) has had on them (Shi’ite militias) will be less tight. He could call for them to take actions against U.S. assets in places like Baghdad’s Green Zone,” he continued, referring to the Iraqi capital’s diplomatic and governmental enclave.
The only “theoretical benefit” the designation could provide is to make it slightly easier for the Justice Department to prosecute people for providing “material support” to the IRGC, he said. The Department already has the authority for similar prosecutions under an executive order signed by President George W. Bush soon after the Sept. 11, 2001, attacks by al Qaeda.
The IRGC is in charge of Iran’s ballistic missile and nuclear programs. Tehran has warned that it has missiles with a range of up to 2,000 km (1,242 miles), putting Israel and U.S. military bases in the region within reach.
Israeli Prime Minister Benjamin Netanyahu, who is up for reelection on Tuesday, warmly welcomed the designation and tweeted “Thank you, my dear friend, U.S. President Donald Trump... for meeting another of my important requests.”
Set up after Iran’s 1979 Islamic Revolution to protect the Shi’ite clerical ruling system, the Guards have great sway in Iran’s political system, controlling swathes of the economy and armed forces.
Their involvement in Iran’s banking and shipping industries could complicate matters with U.S. allies including the European Union. The new designation makes it easier to prosecute EU or other companies or individuals that do business with Iran.
The Iranian currency weakened on Monday, falling to 143,000 rials to the U.S. dollar from Sunday’s rate of 138,000 rials, according to the website Mesghal.com.
The United States has already blacklisted dozens of entities and people for affiliations with the IRGC, but not the organisation as a whole.
Secretary of State Mike Pompeo, a strident critic of Iran, has pushed for the change in U.S. policy as part of the Trump administration’s tough posture towards Tehran.
“This designation is a direct response to an outlaw regime and should surprise no one,” Pompeo said.
The State Department said on Monday the IRGC has been engaged in terrorist activity since its inception, including the 1996 Khobar Towers bombing in Saudi Arabia that killed 19 Americans, and a foiled plan to attack the Saudi ambassador to the United States on U.S. soil.
Previous administrations considered designating the entire IRGC as a foreign terrorist organisation but decided the risk to U.S. forces overseas was too great, former U.S. officials said.
