Why Trump Chose Missiles Over Diplomacy With Iran

Three rounds of nuclear talks. Three failures. And now the Middle East burns.

When President Trump authorized the massive missile strikes that killed Iran's Supreme Leader Ali Khamenei on February 28, 2026, it marked the end of diplomacy and the beginning of something far more dangerous. Tehran's retaliation has already spread across the region, with at least three Americans dead and Gulf states under fire.

But here's what's truly striking: none of this was surprising. From the moment both sides sat down, their red lines were drawn in permanent ink—and they never intersected.

When Negotiation Was Never Really an Option

Iran wanted to talk about one thing only: guarantees that its nuclear program would remain civilian. Everything else—missiles, proxy groups, human rights—was off limits. Essentially, Tehran wanted a return to the 2015 Joint Comprehensive Plan of Action, the Obama-era deal that had worked before Trump scrapped it.

Trump, meanwhile, insisted on exactly what Iran wouldn't discuss: limits on ballistic missiles and an end to support for regional militias. These weren't part of the 2015 agreement because negotiators back then decided that a nuclear deal was better than no deal at all.

"Both sides' publicly stated red lines were incompatible with each other," explains Nina Srinivasan Rathbun, a nonproliferation expert who worked in State Department nuclear diplomacy. "Negotiations were always likely to fail."

For diplomacy to work, both parties need to believe peaceful resolution offers more value than military action. That belief was never present.

The Mirage of Progress

Yet there were moments when breakthrough seemed possible.

With U.S. military buildup in the region, Iran appeared more willing to negotiate on nuclear issues than before. Solutions emerged for uranium enrichment—maintaining minimal domestic capacity for medical isotopes while removing weapons-grade stockpiles.

Before the February 17 Geneva talks, Trump said, "I think they want to make a deal." Iran's Foreign Minister Abbas Araghchi noted progress on "guiding principles."

But optimism evaporated by the February 26 talks. While mediator Oman continued speaking of progress, the U.S. side went notably silent. Reports suggest Trump was displeased with how negotiations had gone, setting the stage for the strikes two days later.

The Backdrop of Force

Throughout the talks, military pressure never stopped building.

The USS Abraham Lincoln carrier group deployed near Iranian waters in January. The USS Gerald R. Ford joined before the final round. Trump warned Iran that "if they don't make a deal, the consequences are very steep."

The calculation seemed clear: Iran, weakened by June 2025 U.S.-Israeli strikes and diminished proxy capabilities, was playing from weakness.

But Tehran signaled it wouldn't back down. Military exercises. Closure of the Strait of Hormuz for live-fire drills. Declarations that Iran wouldn't restrain its response to another attack.

The world is now seeing what that means.

A Familiar Pattern of Failure

Trump isn't the first president to fail at securing a nuclear deal with Iran—though he is the first to respond with military action.

The Biden administration pledged to strengthen the Obama-era agreement in 2021. But Iran had significantly advanced its nuclear capabilities during the years since JCPOA collapsed. Returning to the previous deal would have required Iran to give up new technical achievements for no additional benefits.

That window closed in 2022 when Iran removed all International Atomic Energy Agency surveillance and began enriching uranium to near-weapons levels, stockpiling enough material for several nuclear weapons.

Optimism also existed briefly in spring 2025 during five rounds of indirect talks—until the U.S. bombed Iran's nuclear infrastructure in June as part of a broader Israeli attack.

The Cost of Choosing Force

When I worked in multilateral nuclear diplomacy, we watched North Korea talks fail in 2009 after six years of on-and-off progress. The consequence? A more unstable East Asia and renewed South Korean interest in nuclear weapons.

The same dynamic is now playing out in the Middle East.

Military strikes have killed more than 200 across Iran and the region. A wider war looms. Should the Iranian regime survive, it may now commit fully to developing nuclear weapons—having learned that lacking them provided no deterrent to U.S. and Israeli military action.
