US Defense Secretary Warns of Potential Military Action Against Iran Over Nuclear Program
Amid ongoing international discussions regarding Iran’s nuclear ambitions, U.S. Defense Secretary Pete Hegseth has indicated that military options remain on the table should diplomatic efforts fail to prevent Tehran from acquiring nuclear weapons. This statement follows previous warnings from former President Donald Trump concerning the potential for significant repercussions if Iran advances its alleged nuclear weapons program. The escalating rhetoric underscores the critical juncture in US-Iran relations and the persistent threat of military conflict.
Hegseth Reiterates Firm Stance on Iran’s Nuclear Ambitions
Secretary Hegseth reinforced the gravity of the administration’s position during a recent interview, asserting that the President is “dead serious” about employing the Department of Defense to ensure Iran does not achieve nuclear weaponization should negotiations falter.
“He’s unequivocally clear that Iran must not possess a nuclear weapon,” Hegseth, a former Army National Guard officer, stated on Fox News Sunday Morning Futures. “This has been his consistent stance for two decades.”
Hegseth emphasized the administration’s preference for a peaceful resolution through dialogue, stating, “He’s dead serious about achieving a resolution at the negotiating table, peacefully. This is why he is directly engaged in these talks and has established a clear timeframe.”

However, he stressed the availability of alternative measures, “But he’s equally resolute that should diplomatic solutions prove unsuccessful, other options, including military intervention from my department, are available to guarantee Iran never obtains a nuclear bomb,” thereby raising the specter of armed conflict.
“Military action is not our desired path, but our recent operations against the Houthis and other regional actions demonstrate our capacity to project power effectively and decisively,” Hegseth commented.
“While we seek to avoid military engagement, we are prepared to act if necessary to prevent Iran from developing nuclear weapons.”
Diplomatic Efforts Underway Amid Regional Tensions
Hegseth acknowledged that U.S. Middle East envoy Steve Witkoff has engaged in “productive discussions” with Iranian Foreign Minister Abbas Araghchi recently, though he noted that disagreements persist.
Former President Trump disclosed earlier in the week that the U.S. is engaged in high-level “direct” talks with Iran. This revelation occurred during a meeting at the Oval Office with Israeli Prime Minister Benjamin Netanyahu, a key regional ally in addressing Iranian influence.
“I want Iran to develop into a prosperous and content nation, but nuclear weapons are unacceptable,” Trump declared.
Meanwhile, Iran’s Supreme Leader Ayatollah Ali Khamenei has expressed ambivalence regarding the ongoing negotiations, suggesting that dialogue under duress may be unproductive.
Iran’s Negotiating Position Potentially Weakened by Recent Events
The intensified diplomatic push to resolve the nuclear issue coincides with a period of significant setbacks for Iran, potentially impacting Tehran’s leverage in negotiations.
Iranian-backed proxy forces, including Hamas in Gaza and Hezbollah in Lebanon, have experienced considerable degradation due to Israeli military actions in recent weeks.
Furthermore, facilities associated with Iran’s nuclear and ballistic missile programs reportedly sustained damage in prior incidents.
US Military Actions and Regional Shifts Add Pressure
U.S. airstrikes have targeted Houthi militants in Yemen, who are supported by Iran, striking strategic infrastructure such as oil refineries, airfields, and missile installations.
Adding to Iran’s challenges, a key regional ally, Syrian leader Bashar Assad, was recently removed from power after a prolonged tenure, representing a significant geopolitical shift.
Domestically, the Iranian leadership faces increasing internal pressures as years of international sanctions have severely strained the nation’s economy.
New Sanctions Target Iran’s Nuclear Program
The U.S. Treasury Department has implemented a fresh set of sanctions targeting entities and individuals allegedly playing crucial roles in Iran’s nuclear program, signaling Washington’s intent to intensify economic pressure.
Historical Context: Iran’s Nuclear Program and International Agreements
Under the 2015 nuclear agreement with the Obama administration, Iran’s uranium enrichment was restricted to 3.67 percent, limiting its capacity to produce weapons-grade material.
However, the Trump administration withdrew from this agreement, leading Iran to resume uranium enrichment at higher levels, reportedly reaching up to 60 percent enrichment β a short technical progression from weapons-grade levels.
Reports suggest the previous administration’s decision to abandon the 2015 accord was influenced by a desire to dismantle the legacy of the preceding administration.
