# Decision Point Approaches: What Happens After Trump's Iran Ultimatum Expires

The Current Standoff

The United States and Iran are approaching a critical inflection point in late February/early March 2026, as President Donald Trump's 10-15 day ultimatum to Tehran draws to a close. The massive US military buildup in the Middle East—described by multiple sources as the largest since the 2003 Iraq invasion—is now essentially complete. According to Article 10, the USS Gerald R. Ford carrier strike group entered the Mediterranean on February 20, joining the USS Abraham Lincoln already positioned in the Arabian Sea, creating a dual-carrier presence with unprecedented strike capabilities. According to Article 1 and Article 8, military planning has reached an "advanced stage" with options that go far beyond conventional strikes, including targeting individual Iranian leaders and potentially pursuing regime change in Tehran. This represents a dramatic escalation from Trump's campaign promises to avoid nation-building exercises like those in Iraq and Afghanistan. The diplomatic track has produced mixed signals. Article 14 and Article 17 report that indirect talks in Geneva on February 19 yielded agreement on "guiding principles," but Vice President JD Vance acknowledged that Iran had not accepted US "red lines." The gap between positions remains substantial.

Critical Timeline: The IAEA Factor

A crucial and perhaps determinative element is timing. Article 7 and Article 9 highlight that the International Atomic Energy Agency's Board of Governors is scheduled to meet March 2-6 in Vienna—precisely within Trump's ultimatum window. This creates a potential repeat of June 2025, when Israel launched strikes within 24 hours of an IAEA condemnation resolution. This convergence is unlikely to be coincidental. The IAEA meeting provides both diplomatic cover and a forcing mechanism. If the Board issues another censure or refers Iran to the UN Security Council, it would give the US additional justification for military action while maintaining a veneer of multilateral legitimacy.

Most Likely Scenario: Limited but Significant Strikes

Based on the available evidence, the most probable outcome is a coordinated US-Israeli military operation in the first week of March, timed around the IAEA meeting. However, contrary to some reporting, this is unlikely to be an all-out attempt at regime change through airpower alone. Article 5 features analysis from retired Brigadier General John Teichert, who characterizes the buildup as designed to give Trump "maximum leverage and options." The military deployment serves dual purposes: genuine preparation for strikes if diplomacy fails, and enormous pressure to extract Iranian concessions at the negotiating table. The strike package, if ordered, would likely include: - **Nuclear facilities**: Remaining enrichment sites and concealed program elements that Iran has been rebuilding (Article 14, Article 17) - **Revolutionary Guard bases**: Command and control facilities tied to regional proxy operations - **Missile production sites**: Infrastructure for Iran's ballistic missile program, which has been under reconstruction since June 2025 - **Selective leadership targeting**: High-value individuals in the IRGC and nuclear program, as outlined in Article 1 Article 18 details the specific capabilities now positioned: F-22 and F-35 stealth fighters for initial penetration, EA-18G electronic warfare aircraft to suppress air defenses, F-15E and F-16 fighters for follow-on strikes and air defense, and B-2 bombers on high alert for deep bunker penetration.

Iran's Response Options

Tehran faces difficult choices. Article 11 discusses Israeli intelligence assessments that Iran might launch a preemptive strike, though former intelligence officials rate this as low probability, noting "this is not a suicidal regime." More likely, Iran would absorb an initial strike and respond through: - **Regional proxy attacks**: Targeting US bases across the Middle East (Article 2 reports Iran has declared these "legitimate targets") - **Strait of Hormuz disruption**: Mining or harassment operations to disrupt global oil flows - **Missile/drone barrages**: Against Israel and US regional facilities, similar to the June 2025 response - **Cyber operations**: Attacks on critical infrastructure in the US and allied nations Article 6 outlines seven scenarios, ranging from limited strikes prompting political change to full-scale regional war. The middle scenarios—where Iran survives but adjusts its behavior, or where conflict expands through proxy networks—appear most realistic.

The China Factor

An underappreciated complication is China's positioning. Article 4 reports that a Chinese military attaché recently presented Iran's Air Force commander with a model of the J-20 stealth fighter—a symbolic gesture signaling potential military support. While an actual sale seems unlikely in the immediate timeframe, Beijing's willingness to break from previous neutrality indicates that a US attack on Iran could accelerate China-Iran military cooperation and further fracture global geopolitical alignments.

Prediction: A Deal With Coercion

Despite the war preparations, the most likely outcome remains a coerced diplomatic arrangement reached in the final days before or immediately after the IAEA meeting. Iran's leadership understands the correlation of forces is unfavorable, and Article 5 notes that "Iran would be wise to make a deal. Otherwise, they're going to face the full force of the United States military." However, any agreement will be fragile, heavily weighted toward US demands, and require intrusive verification measures that Iran will resist implementing. The military assets will remain in position for months as a continued pressure mechanism. If strikes do occur, they will be calibrated to degrade Iranian capabilities without triggering uncontrollable escalation—though as Article 3 notes, this would still constitute "the supreme international crime" of aggressive war under international law. The operation would last days to weeks rather than months, with the goal of returning to negotiations from a position of demonstrated military dominance. The March 2 IAEA meeting will serve as the de facto decision point, with the window for diplomatic resolution closing rapidly in the final days of February.
