Iran signed the Nuclear Non-Proliferation Treaty in 1974 and concluded a comprehensive safeguards agreement with the IAEA the same year. The agreement was straightforward: Iran would not pursue nuclear weapons, and in exchange, it would be permitted to develop civilian nuclear energy under international supervision.

What followed over the next three decades was a masterclass in diplomatic deception.

This is the nuclear record. Not allegations. Not geopolitical speculation. Documented findings by the UN's own nuclear watchdog, referenced in US Congressional Research Service reports, confirmed across six US administrations spanning both parties.

The nuclear deception had a twin: the missile deception.

Iran's Supreme Leader Ali Khamenei had imposed a formal 2,000-kilometer range limit on Iranian ballistic missiles in 2017. Jeffrey Lewis of the Middlebury Institute told CNN this was a political decision — Iran was already developing capabilities far beyond that limit, but Khamenei chose not to publicly demonstrate them. Iran's Foreign Minister Araghchi repeated this claim as recently as days before the Diego Garcia launch: "We don't want to be felt as a threat by anybody else in the world."

This statement — made on American television, to an international audience — was a lie. And the lie had a specific purpose: to reassure European governments that they were outside Iran's reach and therefore had no reason to take a harder line against Tehran.

The Diego Garcia attack revealed a range of at least 4,000 kilometers. From Iran, that puts Paris, Rome, Berlin, Warsaw, Bucharest, and most major European capitals within potential striking distance. Military analysts at CSIS noted that Iran had been "testing big, solid missiles for years" and had simply not "shown their cards."

Analysis by the Royal United Services Institute suggests the launch may have involved improvised use of Iran's Simorgh space launch rocket — meaning Iran had found ways to weaponize its civilian space program to achieve intercontinental reach. One analyst noted that the intercepted missile could be "a candidate for the longest-range missile" the United States has ever shot down.

The nuclear and missile programs were not Iran's only deceptions. For forty years, Iran has maintained a sprawling network of terrorist proxies across the Middle East while publicly denying direct involvement in their attacks.

The United States first designated Iran a State Sponsor of Terrorism in 1984 — a designation it has held continuously ever since. The Reagan administration made the designation based on Iran's role in directing the 1983 Beirut Barracks bombing, which killed 241 American servicemembers. That attack was funded and directed by Iran through Hezbollah.

The method is always the same: Iran provides funding, weapons, training, and strategic direction — then denies involvement when those groups commit atrocities. This is not a regime that lied occasionally under pressure. It is a regime that organized its entire financial and foreign policy architecture around the ability to lie.

Here is the question that European leaders must answer — not to Washington, not to Tel Aviv, but to their own citizens:

The EU-3 — France, Germany, United Kingdom — invested years of diplomatic capital in negotiations with Iran. The JCPOA was their crowning achievement. European leaders celebrated it as proof that diplomacy could work, that engagement was more effective than confrontation.

But the JCPOA did not end Iran's nuclear ambitions. It paused some activities while leaving others untouched. It released over $100 billion in frozen Iranian assets — funds that flowed, by Iran's own internal admissions, into the IRGC and its proxy terror networks. It asked the IAEA to formally close its investigation into the military dimensions of Iran's program as a condition of implementation — an extraordinary concession that effectively rewarded deception with diplomatic closure.

And when Iran began systematically violating the JCPOA — exceeding uranium enrichment limits, blocking IAEA access, producing uranium metal with no civilian justification — European governments issued joint statements of concern and called for restraint.

The tragedy is that this moment was entirely predictable. Every arms control analyst, every IAEA report, every State Department terrorism assessment pointed toward exactly this outcome. The Iranian regime does not moderate when given incentives. It does not honor commitments when the pressure is removed. It uses diplomatic processes as cover for continued development and as a mechanism to divide the international coalition against it.

Recognizing this is not hawkishness. It is reading the documented historical record.

This brings us to the most contested question of 2026: was the US-Israel military action against Iran's nuclear and missile infrastructure the right decision?

Set aside political preferences. Set aside personalities. Look only at the strategic facts on the ground at the time the decision was made.

By early 2026, Iran had accumulated enough near-weapons-grade uranium for approximately ten nuclear warheads if further enriched. It had demonstrated ballistic missiles capable of reaching European capitals. It had a satellite program that analysts believed could be repurposed for intercontinental ballistic missile delivery. It had refused IAEA access to multiple declared sites. And it had shown, in the words of IAEA Director General Rafael Grossi, "rapid accumulation of highly-enriched uranium" that represented "a serious concern."

The strategic question was not whether Iran posed a threat. The documented evidence was unambiguous. The question was: at what point does inaction become more dangerous than action?

The case for acting in early 2026 rests on a straightforward logic: a country with nuclear weapons and missiles capable of reaching Europe is orders of magnitude more difficult to deter, contain, or stop than one that does not yet have them. The cost of miscalculation after Iran achieves nuclear capability is not a regional conflict and elevated oil prices — it is permanent, existential leverage over every country within missile range.

Iranian ballistic missile test — the capabilities they denied having

Vice President JD Vance articulated this calculation directly, citing the IAEA's own findings: Iran had been "found in violation of their non-proliferation obligations by the International Atomic Energy Agency, which is hardly a right-wing organization."

The costs of the military action are real: elevated oil prices, regional instability, military casualties, economic disruption. These deserve honest acknowledgment. But these costs must be weighed against what they prevented. A nuclear-armed Iran with missiles that can reach Paris and London is not a problem that can be solved with sanctions and joint statements after the fact. It is a permanent condition — one that fundamentally restructures the security architecture of the entire northern hemisphere.

History will judge whether the action was conducted optimally. But the underlying strategic assessment — that the window for decisive action was closing, and that a nuclear Iran would represent a qualitatively different and far more dangerous world — reflects a clear-eyed reading of the documented evidence that European governments had available and chose not to act on.

On March 24, 2026, German President Frank-Walter Steinmeier addressed the 75th anniversary of Germany's restored Foreign Ministry in Berlin. He called the military campaign against Iran "a fatal political mistake," a violation of international law, and said it "could have been avoided." He added: "Trust in American power politics has been lost — not only among our allies, but across the world."

Let's place that statement next to the documented record.

Mr. Steinmeier, with respect: international law only functions when all parties treat it as binding. Iran treated it as a negotiating costume — worn at the table, discarded in the laboratory. The IAEA found Iran in formal noncompliance in 2005. That was the first time in the agency's history. Not Russia. Not North Korea. Iran — while Europe was still holding diplomatic meetings in Vienna.
