## Introduction

"You will know the result in about 10 days"—when US President Donald Trump made this statement at the first meeting of the "Peace Committee" in Washington, tensions in the Middle East had reached their highest point since the "12-Day War" in June 2025. Two US aircraft carrier strike groups were gathering in the Persian Gulf, hundreds of fighter jets were on standby, and Iran threatened to "sink" US warships. This was not a game of diplomatic rhetoric, but a nuclear brinkmanship scenario in a military simulation.

On February 18, 2026, US envoys Steve Wittekov and Jared Kushner met with Iranian officials in Geneva to discuss Iran's nuclear enrichment program. Iran promised to respond to US demands (complete abandonment of uranium enrichment in exchange for sanctions relief) within two weeks. However, Trump's historical record made this timeline seem particularly ominous—last summer, he had given himself two weeks to decide whether to bomb Iran's Fordow underground nuclear facility, and within days, B-2 stealth bombers were deployed.

## Unprecedented Military Buildup

### Deterrent Signals from Dual Carrier Strike Groups

The scale of US military deployment in the Middle East has surpassed that during the "12-Day War." The USS Abraham Lincoln carrier strike group has been deployed in the Arabian Sea for nearly a month, carrying nine squadrons of aircraft, including F-35 Lightning IIs and F/A-18 Super Hornets. Meanwhile, the world's largest aircraft carrier, the USS Gerald R. Ford, is sailing from the Atlantic to the Mediterranean and is expected to arrive in a few days.

According to an analysis by Matthew Saville, Director of Military Science at the Royal United Services Institute, the two carrier strike groups can "conduct hundreds of strike missions daily for weeks, with intensity exceeding that of the 12-Day War." Even without the Ford, Lincoln's aircraft can conduct over 125 bombing missions daily.

A significant number of military aircraft have been tracked moving to the Middle East: six E-3 Sentry AWACS have been relocated from the US and Japan to Prince Sultan Air Base in Saudi Arabia, which is crucial for real-time command and control. Satellite images of Al Udeid Air Base in Qatar (the regional headquarters of US Central Command) show the deployment of Patriot air defense systems. US destroyers near Cyprus can intercept ballistic missiles aimed at Israel.

### Target List: Nuclear Facilities or Missile Bases?

What are the targets of this military buildup? Options include:

1. **Strikes on Nuclear Facilities Again**: The bombings in June last year did not completely destroy Iran's nuclear program. The Pickaxe Mountain complex near Natanz and the Taleghan 2 facility in Parchin were two nuclear sites that were not attacked during the 12-Day War. According to an assessment by the Institute for Science and International Security (ISIS) in November, Iran "appears unable to enrich uranium or manufacture gas centrifuges in any significant way," but the whereabouts of 440 kilograms of 60% enriched uranium remain uncertain—this is theoretically enough to produce 10 nuclear weapons (if further enriched to over 90% and weaponized).

2. **Ballistic Missile Program**: Israel has been pressuring the US to focus on Iran's ballistic missile program, which is considered the country's most potent military threat. Iran is estimated to possess about 2,000 ballistic missiles, distributed across approximately 25 launch sites nationwide, six of which were not attacked by Israel in June.

3. **Regime Targets**: Last month, Trump promised those protesting the Iranian regime that "help is on the way," but at that time, US military presence was limited. Now, warships and fighter jets are in position, protests have been violently suppressed, and US leaders are turning their attention to Iran's nuclear ambitions.

## Iran's Symmetrical and Asymmetrical Response Capabilities

Iran does not possess an effective air defense system—these systems were easily suppressed by Israeli forces during the brief summer war. Therefore, Iran's most viable form of defense will be retaliation.

### Improved Missile Accuracy

The US and Israel have complex air defense systems, but even so, it is difficult to completely intercept a barrage of ballistic missiles. During the 12-Day War, Iran improved its hit rate: at the start of the war, only 8% of Iranian missiles penetrated defenses, but by June 22 (two days before the end), 10 out of 27 missiles hit Israel—a hit rate of nearly 37%.

### Regional Targets and Maritime Threats

On the evening of February 19, Iran's permanent mission to the United Nations informed Secretary-General Antonio Guterres that if faced with military aggression, Tehran would consider the bases, facilities, and assets of "hostile forces" in the region as legitimate targets.

Iran's Supreme Leader Ali Khamenei threatened to sink US warships. This is not an empty threat—the narrow waters of the Strait of Hormuz, the shallow waters of the Persian Gulf, Iran's anti-ship missiles, fast boat fleets, and mines present a nightmare scenario for the US Navy. In June last year, Iran attempted to use unmanned boats to attack US vessels; although they were repelled, it demonstrated a determination to employ asymmetrical tactics.

### The Russian Factor: Timing of Iran-Russia Naval Exercises

As US-Iran tensions escalate, Russia and Iran are conducting joint naval exercises. This is not only a display of military cooperation but also a signal to Washington: Iran is not isolated. The Russian Foreign Ministry warned that the US military buildup in the Middle East is "escalating tensions." The strategic partnership between Moscow and Tehran has deepened following the Ukraine war—Iran provides drones to Russia, while Russia offers intelligence and potential air defense systems.

## Comparison with the JCPOA: From Multilateral to Unilateral

The 2015 Iran nuclear deal (JCPOA) was a multilateral agreement reached under the Obama administration, involving China, Russia, the UK, France, Germany, and the EU. That negotiation lasted nearly two years and included detailed verification mechanisms and a roadmap for gradual sanctions relief.

Trump's approach during his second term is starkly different:

1. **Unilateral Pressure**: The US is negotiating with Iran alone, and European allies (especially the UK) have made it clear they will not allow RAF Fairford or Diego Garcia in the Indian Ocean to be used for B-2 bomber launches.

2. **Military Priority**: The JCPOA was a "carrot and stick" approach, whereas now it is almost entirely "stick." Trump's ten-day ultimatum resembles a demand for surrender rather than negotiation.

3. **Complete Abandonment vs. Limitations and Verification**: The JCPOA allowed Iran to retain some enrichment capability under strict limitations and verification, while the US now demands "complete abandonment of enrichment in exchange for sanctions relief."

4. **Timeline**: The JCPOA took years of negotiation; now it is ten days.

## Contradictory Positions of Regional Allies

### Israel: Seizing the Opportunity to Root Out?

The government of Israeli Prime Minister Benjamin Netanyahu hopes the US will completely destroy Iran's nuclear capabilities and missile programs. Tel Aviv fears that any short-term agreement will only give Iran breathing room to rebuild. Satellite images provided by Israeli intelligence show that a destroyed building at the Natanz nuclear facility has a new roof (taken on January 30, 2026), and opposition claims that Iran is secretly rebuilding its nuclear program.

### Saudi Arabia: Economy vs. Security

Saudi Arabia has allowed the US to deploy E-3 AWACS on its territory, but Riyadh is cautious about full-scale war for two reasons:

1. **Economic Considerations**: Saudi Arabia is pursuing an economic transformation under its "Vision 2030," and a large-scale war would scare away foreign investment.
2. **Vulnerability of Oil Facilities**: In 2019, Houthi forces (Iran-supported) attacked Saudi oil facilities at Abqaiq and Khurais with drones, causing a 5% disruption in global oil supply. Saudi Arabia fears becoming a target for Iranian retaliation.

### European Union: Division and Powerlessness

The EU hopes to restore the JCPOA but is powerless in the face of Trump's unilateral actions. France, Germany, and the UK (E3) attempted to maintain the nuclear agreement, but after the US unilaterally withdrew in 2018, European companies withdrew from the Iranian market for fear of US secondary sanctions. Now, the EU can only watch from the sidelines, at most offering humanitarian gestures.

## Credibility Analysis of the Ten-Day Deadline

Is Trump's ten-day ultimatum serious? Based on the following factors, the answer may be "both yes and no":

**Evidence Supporting "Seriousness":**
- Unprecedented military buildup (two carrier strike groups, hundreds of aircraft, E-3 AWACS)
- Trump's track record: last year he gave himself two weeks but acted within days
- Domestic political pressure: Republican hawks demand a tough stance on Iran
- Ongoing pressure from Israel

**Evidence Supporting "Bluffing":**
- Consequences of strikes are unpredictable: Iranian missile salvos could hit Israel, Saudi Arabia, or US bases
- Congressional Democrats oppose unauthorized military action
- Oil prices could soar (Strait of Hormuz crisis)
- European allies are uncooperative
- Opposition from China and Russia

The most likely scenario is that Trump hopes to force Iran to make concessions within ten days through extreme pressure. If Iran does not yield, the US may conduct "limited strikes" (similar to last June) rather than full-scale war. However, the definition of "limited strikes" is vague, and once initiated, it is difficult to control escalation.

## Conclusion: Dangerous Brinkmanship

Historical nuclear brinkmanship—such as the 1962 Cuban Missile Crisis—was resolved when both sides had clear red lines and communication channels. Currently, there is a lack of direct diplomatic relations between the US and Iran (with indirect communication through Switzerland and Oman), and the risk of miscalculation is extremely high.

Trump's ten-day ultimatum has pushed the Middle East to a dangerous tipping point. Even if some form of agreement is reached, it is likely to be a compromise under duress rather than a sustainable diplomatic solution. Iran is unlikely to completely abandon its uranium enrichment capabilities—this is viewed as a final means of national sovereignty and deterrence against Israel. The US is also unlikely to accept Iran retaining any enrichment capability.

In the next ten days, three scenarios may unfold in the Middle East:

1. **Diplomatic Breakthrough** (20% probability): Iran makes substantial concessions, the US postpones military action, and a temporary freeze agreement is reached.
2. **Limited Military Strikes** (60% probability): Iran rejects US demands, the US conducts airstrikes on nuclear facilities or missile bases, Iran retaliates against Israel or US bases, escalating the situation but avoiding full-scale war.
3. **Full-Scale Conflict** (20% probability): Strikes trigger an uncontrollable spiral of escalation, including a blockade of the Strait of Hormuz, Israeli ground invasion of Lebanon (to strike Hezbollah), and attacks on Saudi and UAE infrastructure.

Regardless of the scenario, the Middle East is no longer the same as it was before June 2025. Trump's ten-day ultimatum is not only a test for Iran but also a test for the international order, the US alliance system, and the nuclear non-proliferation regime. The countdown has already begun.
