A new analysis from Aaron David Miller, a senior fellow at the Carnegie Endowment for International Peace, characterizes the emerging U.S.-Iran diplomatic framework as a strategic setback for Israel, reflecting deepening fractures in the traditionally close American-Israeli relationship.
Miller told PBS NewsHour's William Brangham that Israeli concerns about the deal are understandable given what he described as existential threats posed by Iran's nuclear program. "On the issue of Iran's nuclear program, the U.S. is Mars and the Israelis are Venus," Miller said.
What the Left Is Saying
Progressive Democrats and left-leaning foreign policy analysts have long advocated for direct U.S.-Iran negotiations as an alternative to military escalation. Senator Chris Murphy of Connecticut has argued that diplomatic engagement offers the only viable path to preventing nuclear proliferation in the region.
Advocates for engagement point to the 2015 Joint Comprehensive Plan of Action as evidence that conditional talks can produce verifiable constraints on Iran's nuclear program. They note that separating the nuclear question from broader regional proxy conflicts could create space for negotiations both sides have indicated they prefer to armed confrontation.
"Where you sit has a lot to do with where you stand," Miller acknowledged, framing Israeli opposition through its own security calculus rather than dismissing it as unfounded.
What the Right Is Saying
Conservative Republicans and pro-Israel advocacy groups view any accommodation of Iran with skepticism. Critics argue that easing sanctions without securing permanent enrichment restrictions would leave Tehran positioned to develop nuclear weapons once constraints expire.
Miller, who has served in both Democratic and Republican administrations negotiating Middle East peace, offered a pointed critique of the current trajectory: "This is a war of choice in which the administration overestimated its own capacity and underestimated the capacity of its adversary." He characterized the emerging diplomatic framework as "a flawed peace of necessity," noting that Iran is unlikely to sever relations with regional proxy groups or accept restrictions on ballistic missile programs.
The former negotiator also addressed reports of strained personal relations between President Trump and Prime Minister Netanyahu, describing unprecedented public airing of private disagreements. "Trump has enormous leverage because of the elections," Miller noted. "Trump cannot elect Benjamin Netanyahu."
What the Numbers Show
Miller outlined specific elements that would determine whether the deal constitutes a meaningful diplomatic achievement: If the administration can secure removal or dilution of Iran's approximately 900 pounds of highly enriched uranium from the country, it would represent a significant gain. A long-term moratorium on enrichment activities could also constitute progress.
The parties remain far apart on timeline. Trump has proposed a 20-year enrichment freeze; Iranian negotiators have countered with 10 years, according to Miller's assessment. "The Iranians have negotiated for decades," he noted. "They play this game a lot better than we do."
Miller also highlighted Iran's territorial demands in any maritime agreement, citing reports that Tehran may seek navigation fees or tolls on strategic waterways despite stated commitments to keep shipping lanes open.
The Bottom Line
The emerging U.S.-Iran framework has exposed fault lines within the American-Israeli relationship that analysts say are more pronounced than at any point in recent memory. Miller's assessment frames the deal as potentially damaging not only to Israeli security concerns but to broader U.S. strategic interests in the region.
"Despite all the tactical military achievements, the degradation of ballistic missiles, drones, all of that, where is the strategic gain?" Miller asked. "Not just for Israel—where is the strategic gain for the United States?"
The deal's success or failure will likely hinge on whether negotiators can bridge the enrichment timeline gap and secure verifiable constraints on Iran's nuclear infrastructure while addressing Iranian demands related to regional standing and economic relief.
