'Verification by Explosives' — Obama's JCPOA vs. Trump's 2026 Deal, Compared on Every Metric

Two Deals. One Country. The Data on Both.
On Sunday evening, hours after the US-Iran peace deal was announced, Robert Greenway — the principal architect of the Abraham Accords — appeared on Fox News and delivered the Trump administration's framing of the new agreement in three sentences.
On Obama's 2015 JCPOA: "They didn't stop the threat — they FUNDED it."
On what Trump's military campaign achieved: "The infrastructure that the Obama and Biden administrations paid for, that I suspect are being mourned right now, ultimately have been destroyed by President Trump."
On verification: "The best verification is done by EXPLOSIVES."
The argument is clear: diplomacy failed, force succeeded, and the 2026 deal is superior because it comes after the destruction of Iranian nuclear infrastructure rather than its preservation under inspections.
The counter-argument is equally clear. Former negotiators and arms control experts point out that Obama's JCPOA dismantled two-thirds of Iran's centrifuges and removed 98% of its enriched uranium — with inspectors on the ground verifying compliance in real time. Trump's 2026 MOU contains no nuclear terms at all, defers the nuclear question to a 60-day window, and comes with a $25 billion price tag in released assets plus a $300 billion reconstruction framework.
Both sides cite data. The data can be compared.
The Comparison Table
Metric | JCPOA (2015) | Trump MOU (2026) |
|---|---|---|
Format | 160-page multilateral agreement | 14-point bilateral MOU |
Negotiating parties | US, UK, France, Germany, Russia, China, EU + Iran (P5+1) | US + Iran, mediated by Pakistan |
Israel involvement | Opposed but informed | Not a party. Called deal a "deep disappointment" |
Enriched uranium | Iran reduced stockpile by 98% (to <300 kg at 3.67% max) | Not addressed. 440.9 kg at 60% enrichment remains |
Centrifuges | Iran dismantled two-thirds of installed centrifuges | Not addressed. All centrifuges remain |
Enrichment cap | 3.67% (far below weapons-grade 90%) | Not specified. Iran permitted to enrich at low levels |
Verification | IAEA continuous monitoring + 24-day access to suspected sites | Not specified in the MOU. Deferred to 60-day talks |
Nuclear commitment | Specific, measurable: stockpile limits, centrifuge caps, facility redesign | Pledge not to develop nuclear weapons (already an NPT obligation since 1968) |
Timeline | Immediate implementation; sunset clauses at 10–15 years | 60-day window for nuclear talks. No nuclear terms in the deal itself |
Missiles | Not addressed (major criticism of JCPOA) | Not addressed (explicitly excluded per Iranian media) |
Proxy groups | Not addressed (major criticism of JCPOA) | Not addressed (explicitly excluded per Iranian media) |
Sanctions relief | Nuclear-related sanctions lifted conditionally, phased | All sanctions suspended immediately |
Assets released | ~$100B in frozen assets (phased, conditional) | $25B released (half upfront) + $300B reconstruction framework |
Duration of compliance | Iran compliant from 2016–2018 (until US withdrawal) | Not yet tested. Deal signed June 14/15, 2026 |
What ended it | Trump withdrew in May 2018 | N/A — deal just signed |
What the Greenway Argument Gets Right
Greenway's core claim — that the JCPOA "funded" Iran — has a documented basis. After the 2015 deal, Iran gained access to approximately $100 billion in frozen assets and sanctions relief. A portion of those funds flowed to Iran's regional proxy network: Hezbollah, the Houthis, Iraqi militias, and Hamas. The Congressional Research Service and multiple intelligence assessments have documented this flow.
The JCPOA also had sunset clauses — enrichment limits expired after 15 years, centrifuge restrictions after 10. Critics argued, with justification, that this gave Iran a guaranteed pathway to nuclear capability by the early 2030s.
And the JCPOA did not address Iran's ballistic missile programme or its support for regional proxies — the same criticism now levelled at Trump's 2026 deal.
What the Greenway Argument Gets Wrong
"The best verification is done by explosives" is a memorable line. The data does not support it.
Before Trump withdrew from the JCPOA in 2018, IAEA inspectors had continuous monitoring access to Iran's nuclear facilities. Iran had reduced its enriched uranium stockpile by 98% — from approximately 8,000 kg to under 300 kg. Two-thirds of its centrifuges were dismantled. Enrichment was capped at 3.67% — far below the 90% weapons-grade threshold.
After Trump withdrew, Iran was no longer bound by these constraints. By June 2025, Iran had:
Rebuilt and expanded its centrifuge capacity with advanced models
Stockpiled 440.9 kg of uranium enriched to 60%
Reached 99% of the centrifuge work needed for weapons-grade enrichment
Expelled IAEA inspectors from monitoring centrifuge manufacturing
The 2026 US-Israeli bombing campaign destroyed portions of this infrastructure. But the nuclear knowledge, the engineering capacity, and the trained workforce cannot be bombed. Iran can rebuild facilities. It cannot un-learn physics.
The JCPOA constrained Iran's nuclear programme verifiably, in real time, with inspectors on the ground. The 2026 MOU contains no nuclear constraints at all. It defers the nuclear question to a 60-day window — with Iran now in a stronger negotiating position (assets released, sanctions suspended, reconstruction funded).
The Irony Both Sides Ignore
The metric on which both deals are identical — and which both sides' advocates ignore — is missiles and proxies.
The JCPOA was criticised for not addressing Iran's ballistic missiles or its regional proxy network. That criticism was valid.
The 2026 MOU also does not address missiles or proxies. Iranian state media explicitly reported that "missiles and resistance groups" are off the agenda.
The same gap that Trump used to justify withdrawing from the JCPOA in 2018 exists in the deal he signed in 2026. The issue that was the stated reason for leaving the first deal is absent from the second.
What Each Deal Cost
The JCPOA Cost
No military operations. Negotiated without a war.
Sanctions relief and asset release. ~$100 billion in frozen assets (phased).
Political cost in Washington. Opposed by Republicans, AIPAC, Israel.
The 2026 MOU Cost
A 107-day war. US strikes on Iran began February 28. Iranian retaliation included Hormuz closure, strikes on US bases in Jordan, Kuwait, and Bahrain.
102 days of Strait closure. The most significant oil supply disruption in history.
Global economic damage. Oil surged from $69 to $157 (Indian basket). India alone lost ₹1,000 crore/day in OMC losses, $20 billion in FPI outflows, and the rupee hit record lows.
$25 billion in released assets + $300 billion reconstruction framework. More than the JCPOA's phased release.
Human cost. Casualties on both sides, civilian infrastructure destroyed in Iran, Israeli strikes in Lebanon continuing through the day of the deal's announcement.
The Question Neither Side Wants to Answer
The JCPOA's defenders must answer: if the deal was working, why did Iran reconstitute its nuclear programme the moment constraints were removed? The speed of Iran's re-enrichment after 2018 suggests the programme was suspended, not dismantled — paused, not ended.
The 2026 deal's defenders must answer: if "verification by explosives" works, why does the MOU contain no nuclear terms? If the bombing destroyed Iran's infrastructure, why is a 60-day negotiation window needed? And if Iran's nuclear programme has been degraded beyond recovery, why does the deal explicitly permit continued enrichment at low levels?
Both deals share a structural limitation: they manage Iran's nuclear trajectory without resolving it. The JCPOA managed it through inspections and caps. The 2026 MOU manages it through a 60-day window and a pledge. Neither eliminates the underlying capability.
Frequently Asked Questions
What did Robert Greenway say about the Iran deals?
Greenway, the Abraham Accords principal architect, argued on Fox News that Obama's JCPOA "funded" Iran's threat through sanctions relief, that Trump's bombing destroyed the infrastructure Obama "paid for," and that "the best verification is done by explosives."
How does the JCPOA compare to the 2026 deal on nuclear terms?
The JCPOA required Iran to reduce enriched uranium by 98%, dismantle two-thirds of centrifuges, cap enrichment at 3.67%, and accept IAEA monitoring. The 2026 MOU contains no nuclear terms — only a pledge not to develop weapons (an existing NPT obligation) and a 60-day window for further talks.
Did both deals address Iran's missiles and proxies?
Neither deal addresses ballistic missiles or regional proxy groups. This was the primary criticism of the JCPOA and is equally absent from the 2026 MOU.
The Bottom Line
The data comparison does not support either side's triumphalism.
The JCPOA was a flawed agreement with real, measurable nuclear constraints — constraints that evaporated the moment the US withdrew. The 2026 MOU is a ceasefire framework with no nuclear constraints at all — and a price tag ($25B + $300B + sanctions suspension) that exceeds the JCPOA's cost while delivering fewer nuclear concessions.
On the specific metric of nuclear verification:
JCPOA: IAEA inspectors, continuous monitoring, 24-day access, 98% uranium reduction, two-thirds centrifuge dismantlement.
2026 MOU: 60-day talks. No inspectors. No caps. No dismantlement.
"The best verification is done by explosives" is a line designed for television. The data says the best verification was done by the IAEA — and it ended when the US withdrew from the deal that authorised it.
