Iran world’s ‘biggest state sponsor of terrorism,’ Mattis says

Newly confirmed Defense Secretary James Mattis sent a strong signal of support to NATO on Monday, reaching out to three critical alliance partners and saying the US had an "'unshakeable commitment to NATO."

(CNN) — US Defense Secretary James Mattis called Iran “the single biggest state sponsor of terrorism in the world” in his first comments on the country Saturday, a day after the Trump administration imposed fresh sanctions over an Iranian ballistic missile test.

Iran and the United States have engaged in tit-for-tat exchanges since US President Donald Trump signed an executive order January 27 banning nationals temporarily from seven Muslim-majority nations of entering the United States. Iran was among those countries.

US District Judge James Robart temporarily stopped Trump’s order Friday night, and the Department of Homeland Security said Saturday it has suspended all actions implementing the order.

Eshaq Jahangiri, Iran’s first vice president, dismissed the remarks from Mattis as “useless claims,” saying that Iran had been instrumental in the fight against ISIS, according to the state-run Islamic Republic News Agency, or IRNA.

As Mattis made his comments Saturday, Iran’s air force was conducting military drills, including missile systems, radar and electronic warfare command and control exercises, in the northern Semnan province, the semiofficial Fars news agency reported.

These drills are aimed at “showing strength, intelligence and readiness for all-round defense against any threat” and are being done “in contempt of sanctions and threats,” the report said.

Iran fired a ballistic missile two days after Trump’s travel ban was announced and vowed to implement “reciprocal measures.”

Mattis said Iran’s “misconduct and misbehavior” would have to be addressed.

“We have a responsibility with the rest of the nations to be absolutely clear with Iran in this regard. It does no good to ignore it. It does no good to dismiss it,” Mattis said in Tokyo, where he met with his Japanese counterpart to discuss security issues.

But he said the recent tensions with Iran did not warrant an increase in the number of US forces in the Middle East.

“We always have the capability to do so, but at this time I don’t think it’s necessary,” he said.

Iran threatens ‘legal restrictions’

The US Treasury Department said Friday it was applying sanctions on 25 individuals and companies connected to Iran’s ballistic missile program and those providing support to Iran’s Islamic Revolutionary Guard Corps’ Quds Force. That included three separate networks linked to supporting the missile program, which the United States opposes.

Trump tweeted Friday that Iran was “playing with fire” and he would not be as “kind” to Tehran as former President Barack Obama.

Iran’s Ministry of Foreign Affairs said Friday it too would ensure “legal restrictions” were imposed on the “American individuals and companies which have a role in aiding extremist and terrorist groups or contribute to the suppression and murder of the defenseless people in the region,” IRNA reported.

The two countries have exchanged explosive language, with the Trump administration putting Iran “on notice” before applying new sanctions and Tehran criticizing what it called the US leader’s “baseless ranting.”

Nuclear deal’s future

The sudden escalation of US-Iranian tensions has raised concerns about the future of the nuclear accord with Iran, which put stringent limits on the country’s nuclear program. It allowed sanctions to be eased and business with Iran to recommence.

Trump has been a longtime critic of the accord, which was brokered after two years of talks with the five members of the UN Security Council and Germany in 2015.

Nasser Hadian, a professor of international relations at Tehran University, told CNN this week it was unlikely the Trump administration would tear up the agreement.

Abandoning the accord “would serve hard-line interests in Iran,” he said.
