Ted Cruz Calls Barack Obama's Iran Nuclear Deal Claim 'an Absolute Lie'

Senator Ted Cruz said Barack Obama's claim that his 2015 nuclear agreement kept Iran from building a bomb is "an absolute lie." He called the former president's Ohio rally speech a preview of how Democrats plan to run against the Iran war through the midterms and into 2028.

The Texas Republican was responding on his podcast, Verdict with Ted Cruz, to Obama's Saturday rally in Ohio for Sherrod Brown, the Democratic Senate candidate, and Amy Acton, the party's nominee for Ohio governor. The midterm elections are eight days away, and Brown leads Republican Senator Jon Husted by 3.4 points in PolitiKool's polling average for Ohio.

What Obama Said in Ohio

Obama mocked the White House ballroom and the paved Rose Garden before turning to the war.

"Iran didn't have nuclear weapons because I had put a deal in place that everybody acknowledges kept them from getting nukes, and I didn't have to fire a missile to do it," Obama said, according to a PolitiFact review of the speech. He blamed the war for higher oil and diesel prices: "Nobody disputes that."

Cruz was blunt.

"So his lie is that Iran did not have nuclear weapons and it wasn't going to get nuclear weapons because the Obama-Iran nuclear deal was going to prevent them from getting nuclear weapons. That is an absolute lie," Cruz said.

Cruz's Case Against the Deal

Cruz made three arguments. First, he said, "Anything that Iran designated as a 'sensitive military facility' was exempted from inspections." Second, "the deal that Obama signed contemplated Iran inspecting itself." He compared that to police asking the Scarface drug lord Tony Montana whether he had any drugs: "Call the Ayatollah, ask if he has nukes. If he says no, trust him." Third, "The entire deal sunsetted in 15 years."

He went further and said, "Barack Obama believes it is perfectly fine for the Ayatollah to have nuclear weapons." That is Cruz's characterization. Obama did not say it.

Cruz said ripping up the deal was "the single most important decision President Trump made in his first term," and he said he had urged Trump to do it.

What the Record Shows

The agreement, formally the Joint Comprehensive Plan of Action, did not expire all at once. Its limits phase out on different schedules. The cap on centrifuges lasts 10 years. The 3.67 percent enrichment cap and the 300-kilogram stockpile limit last 15 years. Monitoring of centrifuge production lasts 20 years, and monitoring of uranium mines and mills lasts 25.

On inspections, the Arms Control Association's summary says requests for access to undeclared sites were overseen by a Joint Commission for 15 years. Disputes over the deal went through a separate resolution process, which included a 15-day step within that commission.

The "inspecting itself" claim traces to a separate 2015 arrangement between Iran and the International Atomic Energy Agency (IAEA) covering the Parchin military complex, under which Iranian staff collected environmental samples. Arms-control experts Mark Hibbs and Thomas Shea wrote for the Carnegie Endowment that the samples were taken "under close observation by IAEA inspectors."

Obama's "everybody acknowledges" line also goes too far. Opposition to the deal was widespread at the time, Cruz's included. PolitiFact found that Obama's reading is "shared by many specialists" and noted that the IAEA reported no major violations while the U.S. remained in the deal.

The IAEA reported that as of June 13, 2025, Iran held 9,874.9 kilograms of enriched uranium. That included 440.9 kilograms enriched to 60 percent, a short technical step from weapons grade.

Iran War, Prices and the 2028 Preview

Cruz predicted that Democrats will tie every price increase to the war: "Everything they are going to blame on President Trump and the Iran war." He also argued, "Now, inflation has dropped dramatically."

The Bureau of Labor Statistics reported that consumer prices rose 3.7 percent in the 12 months ending in September. Prices rose 0.6 percent in September alone, driven by energy. Over the year, the gasoline index rose 34.2 percent and fuel oil rose 74.2 percent.

The Energy Information Administration put diesel at $6.276 a gallon on October 19, up $2.656 from a year earlier. Regular gasoline averaged $4.284, in line with PolitiKool's gas price tracker.

Cruz did not wave Obama off. He called him possibly "the most effective Democrat politician of our lifetime" and said Obama's message is "a real foreshadowing of 100,000 TV commercials that are coming."

Whether that message lands is the open question for the next eight days. Trump's economic approval stands at 29.5 percent in PolitiKool's polling average.
