Margaret Brennan hosted a debate on Iran diplomacy on Face the Nation on August 2, 2026, bringing together Democratic Sen. Mark Kelly of Arizona and Republican Rep. Mike Turner of Ohio to discuss President Trump’s shifting approach to the six-month-old conflict with Iran.
The episode came amid a dramatic diplomatic scramble triggered by Trump’s Friday threat to conduct military action “on levels unseen since World War II” against Iran. Within hours, Trump reversed course, saying he would hold off military strikes after allies including Saudi Arabia urged restraint and Iran signaled a potential diplomatic opening.
Trump told reporters that “the perimeters of a deal” had been agreed to, referring to what diplomatic sources described as progress toward reopening the Strait of Hormuz. However, sources made clear no final agreement had been reached, only signs of movement toward an arrangement to reopen the critical waterway.
Sen. Kelly argued the administration was “flailing” in its approach to ending the war, which has killed 18 Americans and driven up energy costs nationwide. “He’s got a secretary of defense that doesn’t know how to manage this war,” Kelly said, criticizing the strategy of dropping as many munitions as possible and now facing a munitions shortage.
Kelly said Trump needed to put qualified negotiators in charge rather than relying on “his real estate buddy and his son-in-law,” and called for rebuilding alliances with both Gulf Cooperation Council and European allies that he said Trump had alienated. Kelly also expressed skepticism about Trump’s request for additional defense funding, noting the Pentagon had already received over a trillion dollars last year.
Rep. Turner took a harder line on Iran, saying the war should continue until Iran agrees to abandon its nuclear program and reopen the Strait of Hormuz. He defended Trump’s skepticism about Iran’s willingness to negotiate, citing what he called Iran’s history of breaking agreements and dishonest dealings.
Turner said all metrics showed Iran in a declining position economically and militarily, suggesting Tehran would eventually be forced to the negotiating table. When pressed on whether he would support a deal “sight unseen,” Turner said the administration had set clear goals: Iran must abandon nuclear ambitions and reopen the strait for commerce.
The debate underscored a fundamental disagreement between Democrats and Republicans over the war’s trajectory. CBS polling showed 32 percent of Americans backed Trump and GOP approach to Iran, while only 30 percent supported Democrats’ position, despite the war being broadly unpopular.
Both Kelly and Turner acknowledged the administration had not shared sufficient detail with Congress about its Iran strategy, even as the conflict entered its sixth month. Turner said Congress registered across both chambers that “the Pentagon needs to be sharing more information with Congress.”
