US Secretary Rubio Frames Iran Strike As Necessary To Halt Nuclear Progress

U.S. Secretary of State Marco Rubio has strongly defended recent American military strikes against Iran’s nuclear and weapons infrastructure, describing the action as “our last best chance” to prevent Tehran from acquiring nuclear weapons and shielding that program with a powerful arsenal of missiles and drones. Rubio’s remarks, delivered in a video posted on the White House’s X (formerly Twitter) account and reiterated in multiple media engagements, outline Washington’s rationale for the timing and scale of the offensive after weeks of escalating regional conflict.

Rubio argued that Iran’s recent military buildup posed a dual threat — not only advancing its nuclear ambitions but also creating a so‑called “conventional shield” of ballistic missiles and armed drones that could make any future intervention ineffective. “We were on the verge of an Iran that had so many missiles and so many drones that no one could do anything about their nuclear weapons program in the future,” Rubio said, adding that preventing such an outcome justified the strike now.

In justifying the action, the U.S. Secretary of State stressed that Tehran had repeatedly rejected opportunities for a peaceful, civilian nuclear program, preferring instead to build facilities underground and away from international scrutiny. He maintained that the recent operation was aimed at dismantling Iran’s conventional military capabilities without seeking full regime change, a framing echoed by senior U.S. officials including President Donald Trump.

The military offensive — launched on February 28 alongside Israeli forces — has targeted thousands of Iranian sites, including missile bases, drone depots, and key nuclear facilities. U.S. leadership asserts that these strikes have slowed Tehran’s nuclear progress and degraded its ability to defend that program. Critics, however, have questioned the legal basis for the intervention and warned of broader regional escalation.

Rubio also addressed concerns about the war’s duration and objectives, saying Washington could see the “finish line” and describing ongoing communications between U.S. and Iranian intermediaries that could pave the way for negotiations. He defended President Trump’s messaging and outlined hopes for compelling Tehran to engage seriously on halting its nuclear ambitions.

The conflict has drawn international attention, with global markets responding to disruptions in the Strait of Hormuz — a critical waterway for oil shipments — and allies debating their roles in the region. As the U.S. maintains pressure on Iran, diplomatic and military developments continue to unfold, shaping one of the most consequential foreign policy challenges of the year.
