Updated Assessment on Iranian Response Scenarios as at 0600 ET June 16

Executive Summary

The conflict between Israel and Iran has escalated dramatically since Israel launched Operation Rising Lion on June 12–13, 2025. The operation began with a surprise Israeli airstrike aimed at dismantling Iran’s nuclear and missile capabilities, targeting both military and nuclear infrastructure. In response, Iran has launched multiple waves of ballistic missile attacks on Israeli cities, resulting in significant civilian casualties and widespread destruction on both sides.

1. Likely Iranian Response Scenarios

• Direct Military Retaliation: Iran may continue ballistic missile strikes against Israeli cities and critical infrastructure, leveraging its remaining missile arsenal.

• Proxy Activation: Iran could activate Hezbollah in Lebanon and Iraqi Shia militias to open secondary fronts, forcing Israel to fight on multiple theaters.

• Asymmetric Warfare: Increased focus on cyberattacks, sabotage, and terrorism targeting Israeli and Western interests globally.

• Nuclear Acceleration: Iran may announce withdrawal from the NPT and accelerate uranium enrichment to weapons-grade levels.

2. Impact on Iran's Strategic Capabilities

• Military: Loss of senior leadership and missile bases degrades Iran's command-and-control and precision strike capabilities.

• Nuclear Program: Damage to Natanz and Fordow slows but does not halt uranium enrichment; underground facilities remain intact.

• Proxy Network: While degraded, proxies like Hezbollah and Iraqi militias can still inflict harm, though their effectiveness may wane without direct Iranian support.

3. Escalation Pathways

• Hezbollah Activation: Hezbollah rocket attacks on northern Israel could draw in Lebanon.

• Houthi Escalation: Increased attacks on Red Sea shipping and Saudi/UAE targets.

• US Involvement: Direct US military support for Israel could expand the conflict.

• Nuclear Brinkmanship: Iran's acceleration of nuclear enrichment could prompt further Israeli strikes.

Key Decision Points:

• Iranian Supreme Leader's willingness to escalate despite regime instability.

• US policy on military support to Israel.

• Saudi/UAE calculus on intervention vs. neutrality.

4. Domestic Upheaval Threshold

• Economic Collapse: Iran's economy, already strained, may face further instability if energy infrastructure is targeted.

• Regime Legitimacy: Significant civilian casualties and military defeats could erode public support.

• Protest Movement: Renewed anti-regime protests, particularly if leadership appears weak or divided.

Timeline: 3–6 months if Iran faces sustained military pressure and economic sanctions.

Key Recommendations

• De-escalation Efforts: International community should prioritize diplomatic engagement.

• Military Preparedness: Israel and US should prepare for potential proxy escalation.

• Economic Contingency Planning: Plan for potential disruptions to global oil markets.

Limitations

• Uncertainty: Iran's nuclear restart timeline remains unclear.

• Proxy Loyalty: Hezbollah's willingness to engage may be limited by its own domestic pressures.

• US-Israel Coordination: Strategic objectives may diverge, complicating joint planning.

Next Steps

• Monitor Iranian Supreme Leader's public statements.

• Assess Hezbollah's military readiness in Lebanon.

• Evaluate US-Israel military coordination mechanisms.

Latest Updates on the Conflict

Key Developments

• Operation Rising Lion: Israeli Prime Minister Benjamin Netanyahu described the operation as a "deliberate military action aimed at mitigating the Iranian threat to Israel's very existence," emphasizing that Iran had made unprecedented moves to weaponize enriched uranium, posing an immediate threat to Israel.

• Targets and Tactics: Israel targeted Iran’s nuclear facilities (notably Natanz, Fordow, and Piranshahr), ballistic missile bases (Kermanshah, Tabriz), and military leadership, including top IRGC officers and nuclear scientists. Israel also struck Iranian energy infrastructure, including oil refineries and fuel depots.

• Iranian Response: Iran retaliated with over 270 ballistic missile launches at Israel since Friday, with 22 missiles breaching Israel’s air defenses and causing significant damage and casualties. Iran has also threatened "unleash hell" and has increased its targeting of Israeli civilian areas.

  • Haifa Oil Refinery: Damaged by Iranian missile strikes, with fires reported.

  • Airport Closure: Israel’s main international airport and airspace closed for three consecutive days due to ongoing missile threats.

Military and Leadership Losses

• Iran: High-profile casualties include Revolutionary Guard intelligence chief Mohammad Kazemi, his deputy, and other top IRGC officers and nuclear scientists.

• Israel: No senior military or political leaders reported killed, but significant civilian casualties and destruction in urban centers.

International Response

• G7 Summit: World leaders, including German Chancellor Friedrich Merz and U.S. President Donald Trump, are prioritizing the Israel-Iran crisis at the ongoing G7 summit in Canada. Objectives include preventing Iran from acquiring nuclear arms, affirming Israel’s right to self-defense, and seeking diplomatic solutions.

• U.S. Involvement: The U.S. has denied direct involvement in the strikes but has assisted Israel in intercepting Iranian missiles. President Trump has praised Israel’s actions and called for a deal to limit Iran’s nuclear program.

Current Status and Outlook

• Ongoing Strikes: Both sides continue to launch attacks, with Israel claiming air superiority over Tehran and Iran threatening further escalation.

• Risk of Regional Conflict: The escalating violence has raised fears of a broader regional war, with global leaders urging restraint and diplomatic solutions.

• Humanitarian Impact: Civilian casualties and infrastructure damage are mounting, with rescue teams struggling to contain fires and recover victims in both countries.

EXECUTIVE SUMMARY

The Israeli strikes under Operation Rising Lion have created unprecedented instability in the Middle East, with cascading effects that will reshape regional dynamics for years. Iran faces its most severe military and political crisis since 1979, but retains significant asymmetric capabilities. The risk of broader regional war remains HIGH, with multiple escalation pathways active. US policy faces critical decision points in the next 72-96 hours that will determine whether this conflict expands or stabilizes.

KEY ASSESSMENTS

1. MOST LIKELY IRANIAN RESPONSE SCENARIOS (72-96 HOURS)

MOST LIKELY (65% Probability): Calibrated Escalation

• Iran will execute a multi-domain response combining:

• Limited direct military strikes on Israeli energy/water infrastructure

• Activation of proxy forces for harassment operations (not full-scale war)

• Cyber attacks on Israeli critical infrastructure

• Accelerated nuclear program activities (enrichment to 90%)

• Oil tanker seizures in Strait of Hormuz

DANGEROUS ALTERNATIVE (25% Probability): Strategic Miscalculation

• Regime hardliners push for demonstration of strength:

• Mass missile barrages overwhelming Iron Dome (500+ missiles)

• Full Hezbollah activation despite degraded capabilities

• Direct attacks on US forces in Iraq/Syria

• Mining of Strait of Hormuz

• Activation of sleeper cells for terror attacks

LEAST LIKELY (10% Probability): De-escalation

• Regime prioritizes survival through restraint:

• Limited symbolic responses only

• Back-channel negotiations through Oman/Qatar

• Focus on domestic control and nuclear program

2. IMPACT ON IRANIAN STRATEGIC CAPABILITIES

Military Command Structure

• Loss of 40% of senior IRGC leadership creates severe C2 disruption
