Trump Ultimatum to Iran: New Strike Threatened as Military Buildup Grows

Renewed U.S. Pressure on Iran’s Nuclear Program

U.S. President Donald Trump issued a new ultimatum to Iran on Jan. 28, stating that military strikes remain an option if Tehran does not agree to limits on its nuclear weapons program. The warning followed weeks of unrest inside Iran and stalled diplomatic discussions over nuclear and ballistic missile constraints. Trump reiterated that Washington’s objective is to prevent Iran from acquiring nuclear weapons, while signaling that negotiations remain preferable to force.

Nationwide Protests and Violent Suppression

Iran experienced widespread protests earlier in January, initially driven by high inflation and the sharp depreciation of the Iranian rial. The demonstrations rapidly evolved into political unrest, with protesters calling for the removal of Supreme Leader Ayatollah Ali Khamenei. Reports indicated protests in more than 100 cities and towns, involving tens to hundreds of thousands of participants. At their peak on Jan. 8–9, the demonstrations represented one of the largest uprisings in Iran’s recent history.

The protests were ultimately suppressed by Iranian security forces. Casualty figures vary significantly by source. Iran’s Human Rights Activists News Agency reported at least 6,092 deaths, with more than 17,000 cases under investigation. Other outlets, citing Iranian Health Ministry sources or opposition-linked media, have estimated fatalities ranging from 30,000 to more than 36,000. Iranian authorities have not released comprehensive official figures.

U.S. Deliberations and Regional Constraints

Analysts say the U.S. response was delayed in part due to limited military assets in the region at the height of the unrest. A U.S. carrier strike group previously deployed to the area had been reassigned elsewhere, reducing immediate strike options. Questions also emerged within the administration over the effectiveness and objectives of potential attacks, including whether strikes would aim to deter further repression, target nuclear facilities, or pursue broader political goals.

Regional dynamics further complicated decision-making. Several U.S. allies in the Middle East expressed reluctance to support military action, citing fears of Iranian retaliation and insufficient missile defense coverage. Israel, despite its longstanding opposition to Iran’s nuclear ambitions, reportedly urged caution. The New York Times reported that Israeli Prime Minister Benjamin Netanyahu asked Trump to delay any strike.

Diplomatic Maneuvering and Russian Involvement

Russia, a key ally of Tehran, offered to mediate between Iran, the United States, and Israel. Russian President Vladimir Putin held separate calls with Netanyahu and Iranian President Masoud Pezeshkian in mid-January. Analysts, however, assess Moscow’s leverage over Tehran as limited, reducing the likelihood of a negotiated breakthrough through Russian channels.

Military Buildup Signals Escalation Risk

Despite earlier hesitations, the United States has increased its military presence around Iran. In recent weeks, additional aircraft and naval assets have been deployed to regional bases, including the arrival of a U.S. aircraft carrier and supporting warships in the Persian Gulf on Jan. 26. CNN reported that the administration is considering strikes following failed preliminary talks on nuclear and missile issues.

Potential targets discussed by analysts include nuclear facilities, government infrastructure, and security organizations such as the Islamic Revolutionary Guard Corps and Basij units. While no final decision has been announced, the buildup suggests that military options remain actively under consideration.
