Sen. Ted Cruz (R-TX) argued on Wednesday that sanctions on Iran’s nuclear program can’t be separated from other sanctions on the regime as part of a nuclear deal, comparing the approach apparently being taken by the Trump administration to that of the Obama administration.

Secretary of State Marco Rubio has said in congressional testimony this week that talks with Tehran have revolved solely around Iran’s nuclear program and have not addressed its sponsorship of terrorism or its ballistic missile program, but said that sanctions related to terrorism and missiles would remain in place if those issues are not addressed in a potential deal.

“The Obama administration invented the category of ‘nuclear sanctions’ as an excuse to give the Ayatollah whatever he wanted for a nuclear deal,” Sen. Ted Cruz (R-TX) said to Jewish Insider. 

“It has nothing to do with how Congress passed or past presidents implemented sanctions against the Iranian regime, which was to use our most powerful sanctions against the full range of Iran’s aggression. President Trump rightly refused to certify and then withdrew from the deal because he said that lifting these ‘nuclear sanctions’ gave Iran too much for too little benefit,” he continued.

Congressional Republicans argued in the past, when the original nuclear deal included a similar formula, that the distinctions between nuclear and non-nuclear sanctions were largely specious. Those same lawmakers have maintained that any new funding the regime received would ultimately fuel proxy terrorism and regional destabilization, regardless of the targets of those sanctions.

Sen. Thom Tillis (R-NC) expressed confidence that the Trump administration understood that any deal must be multi-faceted, though he noted that Congressional Republicans haven’t been briefed on the talks.

“I have to believe at the end of the day, they realize that it’s not just about enrichment, but it’s all the other enabling capabilities, because the reality is the world’s a dangerous place and if they had that underlying capability, maybe then they’ll build their own bomb,” Tillis told JI.

“We got to support Israel. Iran uses proxies to attack America and Israel, they chant ‘Death to America.’ So what they’ve got to do is they’ve got to stop enriching uranium, that’s number one. And number two, we’ve got to make sure they have no money to give their proxies,” Sen. Rick Scott (R-FL) said when asked his position on a deal.

Sen. James Lankford (R-OK) told JI he hadn’t kept up with Rubio’s testimony, but said that addressing Iran’s proxy terrorism is crucial.

“Iran’s the largest state sponsor of terrorism. Israel is fighting proxies all the way around them. The entire region’s destabilized. Egypt is struggling economically because of the Houthis and what they’re doing,” Lankford said. “The proxies are the problem in the area and you can’t disconnect Iran and the regime and what they’re doing in the entire region to destabilize the region.”

Another Senate Republican, speaking on condition of anonymity to speak candidly, said he has faith in Rubio, but that an arrangement as outlined by Rubio would require “an awful lot of trust built into it, and I don’t trust Iran.”

“Money is obviously fungible. And the whole point of proxies is you can do whatever you want without doing whatever you want [directly],” the senator said. “There’s just an awful lot of trust built into.”

The senator said, “There’s probably a time where I’d be willing to give them a little bit of room, but they’re an awfully long ways down the road, so I don’t know. I just hope they keep a very, very tight grip on a very, very short leash.”

Sen. Lindsey Graham (R-SC) told JI that, “I like the American position, the administration’s position of no enrichment, complete dismantlement … and [would] have to include their missile program.”

“Anything short of that would be inadequate,” he added.

Sen. Mike Rounds (R-SD) similarly argued that a deal around Iran’s nuclear weapons would likely include addressing Iran’s pursuit of intercontinental ballistic missiles. He added that Iran should not receive any sanctions relief without addressing its nuclear buildup.

Other senators seem to be focusing their attention more on ensuring that dismantling Iran’s enrichment remains a red line for the United States.

“At the end of the day, we’ve got to see what the final package is,” Sen. Pete Ricketts (R-NE), who recently led nearly all Senate Republicans on a letter insisting on full dismantlement, said. “The biggest issue is going to be the enrichment part. If we can crack the enrichment nut, that’s a big deal.”

Sen. John Kennedy (R-LA) similarly said, “The president’s been very clear. I think the Republican side of the aisle in the Senate has been very clear. No enrichment, zero, zilch, nada, no centrifuges. The Iranian leadership doesn’t need it. They can import uranium for civil nuclear energy, so they can either take it or leave it. We can do it the easy way, the hard way.”
