The June 2025 direct war between Israel and Iran marks the most significant open military conflict in the Middle East since the 2003 Iraq War, and the first-ever direct, full-spectrum confrontation between the two arch-rivals.
Triggered by Israeli preemptive airstrikes on Iranian nuclear and military targets, and followed by unprecedented Iranian missile and drone retaliation, the conflict represents the culmination of decades of proxy warfare, nuclear tension, and ideological confrontation.
At the center are two long-entrenched leaders: Iran’s Supreme Leader Ali Khamenei, who views confrontation with Israel as a religious and strategic imperative, and Israel’s Prime Minister Benjamin Netanyahu, who has staked his political survival on preventing Iran from acquiring nuclear weapons.
Their decisions, shaped by internal political pressures and personal legacies, accelerated a strategic rivalry into full-scale war.
This article breaks down the war’s roots, escalation timeline, leadership dynamics, and potential outcomes in a geopolitical context.
Historical Background: A Long March to Open Hostilities
Iran’s Strategic Vision Since 1979
Iran’s posture toward Israel has been adversarial since the Islamic Revolution. Under Ayatollah Khomeini and then Khamenei, Iran adopted the doctrine of “Resistance Axis,” which includes support for Hezbollah, Hamas, and various Shi’a militias across the Middle East. Iran’s ideological stance against Israel, which it does not recognize, has been paired with practical efforts to build deterrent capabilities—especially its nuclear and ballistic missile programs.
For decades, Tehran’s strategy relied on asymmetric warfare:
- Training and arming proxies in Lebanon, Gaza, Iraq, Syria, and Yemen
- Cyberattacks and regional subversion
- Cautious advancement of nuclear technology under layers of deniability
Israel’s Red Lines and Doctrinal Shifts
Israel, by contrast, has always treated a nuclear-capable Iran as an existential threat. Since the mid-1990s, its military and intelligence services have prioritized Iran as the top threat.
The turning point came in 2018 when Netanyahu revealed captured Iranian nuclear archives, demonstrating continued weaponization research despite the 2015 nuclear deal (JCPOA).
In response, Israel adopted an unofficial doctrine of “campaign between wars” (Hebrew: mabam), which included:
- Covert operations (e.g., assassinations of Iranian scientists, sabotage in Natanz)
- Airstrikes on IRGC positions in Syria and Iraq
- Cyber warfare targeting infrastructure
Despite these actions, the conflict remained indirect—until 2025.
Leadership Breakdown: Netanyahu vs. Khamenei
Ali Khamenei – Supreme Leader of Iran
Position and Authority: Khamenei is Iran’s highest-ranking political and religious figure. As Supreme Leader, he controls the military, judiciary, media, and foreign policy apparatus. His decisions are final in matters of war and peace.
Worldview: Deeply anti-Zionist and anti-Western. Views Israel as an illegitimate occupier and considers its existence a religious affront. Publicly frames confrontation with Israel as a religious obligation and national necessity.
Strategic Legacy: For over three decades, Khamenei has prioritized building Iran’s strategic deterrent: nuclear capability, missile arsenals, and regional proxy networks (Hezbollah, Hamas, Houthis, PMF in Iraq, and militias in Syria). He sees these tools as critical to countering Israeli and American influence.
Internal Pressures: Faces rising dissent over economic decline, international isolation, and deadly internal crackdowns (notably the 2022–2023 Mahsa Amini protests). Uses external conflict to redirect public frustration toward a unifying national “resistance” narrative.
Military Alignment: Fully aligned with the Islamic Revolutionary Guard Corps (IRGC), particularly its Quds Force. In recent years, has empowered hardliners, sidelining moderate voices from foreign and nuclear policy.
Decision to Escalate: Interprets Israeli strikes as not only a military threat but a direct challenge to Iran’s sovereignty and deterrent credibility. Authorizes retaliation to preserve regime prestige and strategic balance.
Benjamin Netanyahu – Prime Minister of Israel
Position and Authority: Israel’s longest-serving prime minister. Heads a right-wing coalition government with strong nationalist and religious factions. Exercises considerable influence over military and intelligence decisions, especially on Iran.
Worldview: Considers Iran the greatest threat to Jewish survival in the 21st century. Views a nuclear Iran as an existential danger. Frames Israel as the sole democratic bulwark against radical Islamic regimes in the Middle East.
Strategic Legacy: Has built his political brand on confronting Iran. Oversaw Mossad operations to sabotage Iran’s nuclear program. Lobbied aggressively against the JCPOA and championed preemptive doctrine over deterrence.
Internal Pressures: Faces intense domestic criticism over judicial reforms, civil unrest, and declining public trust in government institutions. Critics argue that his decisions are increasingly driven by personal political survival.
Military Posture: Highly supportive of aggressive IDF actions, especially cyber, intelligence, and airstrike operations. Maintains direct communication with top military brass. Less inclined to seek U.S. permission for unilateral strikes than previous leaders.
Decision to Escalate: Believed Iran had crossed a nuclear red line and chose to act preemptively, gambling that regional and international fallout would be outweighed by the strategic gain of delaying or destroying Iran’s breakout capability.
Contrasting Leadership Styles
Khamenei is slow-moving, ideology-driven, and favors long-term regional entrenchment through proxies and covert operations. He escalates when deterrence or legitimacy is threatened.
Netanyahu is tactically aggressive, risk-tolerant, and heavily influenced by short-term political calculation. He escalates when he believes that delay will result in irreversible strategic disadvantage.
Khamenei favors asymmetric, attritional conflict through missile warfare and regional militias.
Netanyahu favors technologically superior, high-precision, short-duration strikes to maintain military superiority

Confirmed deaths from missile hits include at least one fatality, plus undisclosed military casualties .
Overall Trends and Critical Observations
Most military casualties on both sides occurred during precision strikes or retaliatory missile attacks
Civilian deaths have increased in urban environments where military infrastructure is embedded
Casualty numbers are rising daily due to the delayed access of rescue teams and ongoing operations
Information suppression by both governments, especially in Iran and Hezbollah zones, has slowed independent verification
Regional humanitarian agencies warn of a worsening medical crisis, especially if the air campaign continues into next week
Military Capabilities and Strategic Objectives
🇮🇱 Israel – Military Capabilities
Air Power
Israel maintains one of the most advanced air forces in the Middle East, with:
- Over 300 combat aircraft, including F-15s, F-16Is, and F-35I “Adir” stealth fighters.
- Long-range strike capability and proven experience in precision bombing over hostile airspace (e.g., Syria, Gaza, Lebanon).
- Air-refueling tankers and drones extend operational reach deep into Iran.
Missile and Air Defense
Operates a multi-layered missile defense system:
Iron Dome: Intercepts short-range rockets.
David’s Sling: Defends against medium-range missiles.
Arrow 2/3: Targets long-range ballistic threats, including those from Iran.
All systems are battle-tested and frequently upgraded in partnership with the United States.
Cyber and Electronic Warfare
Israel has high-level cyber capabilities, led by Unit 8200.
Responsible for Stuxnet, the first cyberattack to physically damage Iran’s nuclear infrastructure (co-developed with the U.S.).
Continuously targets Iranian infrastructure, including defense networks, missile guidance systems, and nuclear research.
Nuclear Capability
Israel maintains a policy of deliberate ambiguity, but is widely believed to possess 80–90 nuclear warheads, deliverable via aircraft, submarines, and ballistic missiles.
Israel’s Jericho III missile can reportedly reach Iran with high accuracy.
Naval Reach
Small but capable navy with Dolphin-class submarines, some reportedly nuclear-armed and second-strike capable.
Presence in the Red Sea and Eastern Mediterranean ensures regional maritime deterrence.
🇮🇱 Israel – Strategic Objectives
1. Prevent Iran from acquiring a nuclear weapon by any means necessary—diplomatic, cyber, or military.
2. Maintain regional air superiority and prevent Iranian entrenchment in Syria, Lebanon, and Gaza.
3. Enforce red lines on Iranian missile development and nuclear breakout thresholds.
4. Deter Hezbollah and Hamas from joining Iran in full-scale escalation.
5. Protect civilian populations through layered defense and rapid retaliation.
6. Preserve strategic independence by acting even without U.S. approval if core national security is threatened.
🇮🇷 Iran – Military Capabilities
Missile Arsenal
Iran possesses the largest missile inventory in the Middle East, estimated at over 3,000 ballistic and cruise missiles.
Includes Shahab, Sejjil, Fateh-110, and Zolfaghar systems, some with ranges exceeding 2,000 km—capable of hitting Israel.
Increasing accuracy and payload capacity due to sustained investment in solid-fuel systems.
Drones (UAVs)
Iran has deployed an extensive fleet of drones including:
Shahed-136, Mohajer-6, and Fotros for surveillance and long-range attacks.
Drones have been exported to and used by Hezbollah, Houthis, and Russia (in Ukraine).
Used in the 2025 conflict to penetrate Israeli airspace and test missile defense systems.
Air Force
Iran’s conventional air force is outdated:
Operates aging U.S.-made F-4s, F-5s, and F-14s from before the 1979 revolution.
However, has begun inducting Russian Su-35s and developing indigenous jets like the Kowsar, though effectiveness remains limited.
Naval Forces
Iranian navy is divided between the regular Navy (IRIN) and IRGC Navy:
Operates fast attack boats, submarines, and anti-ship missiles in the Persian Gulf and Strait of Hormuz.
Uses asymmetric tactics: swarm attacks, sea mines, and small boat harassment.
Cyber Operations
IRGC’s “Cyber Army” engages in attacks on foreign infrastructure, including Israeli water systems and transport networks.
Iran-linked groups have targeted critical infrastructure in the U.S. and Gulf states.
🇮🇷 Iran – Strategic Objectives
1. Preserve the Islamic Republic’s regional deterrence and credibility in the face of Israeli attacks.
2. Respond forcefully to Israeli strikes to maintain internal legitimacy and project strength across the “Axis of Resistance.”
3. Delay or complicate Israeli preemptive action through proxy conflicts (e.g., Hezbollah, Hamas, Houthis).
4. Deter broader U.S. intervention by showing missile reach and asymmetric capabilities.
5. Keep nuclear program viable, even if not weaponized immediately, to retain long-term leverage.
6. Exploit global divisions, including rifts between the U.S., Russia, and China, to limit diplomatic isolation.
De-escalation Pathways
1. Third-Party Mediation (Turkey, Qatar, Oman)
Countries with open channels to both Israel and Iran may broker indirect talks.
Qatar and Oman have historically hosted backchannel diplomacy (e.g., U.S.–Iran nuclear talks).
Turkey may seek to elevate its regional status by mediating temporary ceasefires or technical agreements (e.g., prisoner exchanges, no-strike zones).
Feasibility: Moderate. Iran may accept, but Israel remains skeptical of mediators tied to the Muslim Brotherhood or soft on Hamas.
2. U.S.-Brokered Strategic Pause
The U.S. could offer a framework involving:
Immediate cessation of hostilities.
A new nuclear cap agreement for Iran (e.g., freezing enrichment at 60%).
Security guarantees for Israel, possibly with expanded missile defense deployments.
Expanded humanitarian corridors and reconstruction for impacted regions.
Feasibility: Low–moderate. Politically difficult for U.S. leaders amid election cycles; Iran may resist constraints without sanctions relief.
3. UN Security Council “Grand Bargain”
Proposed multilateral resolution with:
Ceasefire monitoring mission.
No-fly zones over critical nuclear areas.
International arbitration over proxy group funding (e.g., Hezbollah, Houthis).
Gradual sanctions rollback in exchange for verifiable disarmament steps.
Feasibility: Low. Russia and China may veto resolutions seen as favoring the U.S. or Israel. Iran distrusts UN enforcement capacity.
4. Backchannel Israeli–Iranian Intelligence Talks
Both countries have occasionally engaged via neutral intermediaries like Switzerland.
A deal might focus on:
Avoiding direct strikes on leadership or civilian centers.
Establishing “red lines” (e.g., no attacks on oil refineries, nuclear scientists).
Information-sharing to avoid false-flag provocations from third parties.
Feasibility: Medium. Requires trust that is presently absent, but may gain momentum if direct conflict becomes unsustainable.
5. Proxy Management Agreements
The quickest route to de-escalation may not lie in Tehran or Jerusalem—but in managing Hezbollah, Hamas, and Iraqi militias.
External actors (e.g., France with Lebanon, Turkey with Hamas, U.S. with Iraq) may reach:
Quiet understandings to restrain local actors.
Conditional funding, disarmament, or political reintegration paths.
Feasibility: Medium–high. These groups are responsive to funding pressure and survival logic; deals are easier to broker than with states.
Final Thoughts: War Without Victory, Peace Without Trust
The Israel–Iran war has shattered the illusion that their rivalry could be contained through proxies. With both sides now in direct confrontation, neither has a clear path to victory—only the certainty of growing regional and global instability. Israel risks military overreach; Iran risks internal collapse.
Global powers call for restraint, but trust is scarce and diplomacy is fragile. Unless de-escalation efforts gain urgent traction, this war may settle into a prolonged, dangerous stalemate—where every strike invites a deadlier response, and peace grows more elusive with each passing day.
