Introduction: The Ideological Core of Iran’s Anti-Israel Doctrine
Understanding the contemporary geopolitical dynamics of the Middle East requires examining one of the Islamic Republic of Iran’s defining ideological principles: its enduring theological and political opposition to the State of Israel.
Since the 1979 Islamic Revolution, Ayatollah Ruhollah Khomeini fundamentally transformed Iranian foreign policy. The pragmatic strategic relationship maintained with Israel under the Shah was replaced by an explicitly revolutionary doctrine portraying the “Zionist entity” as illegitimate and ultimately destined for elimination.
This position extends beyond domestic political rhetoric. It functions as a central pillar of ideological legitimacy for the clerical establishment while reinforcing Tehran’s claim to leadership within the broader “Axis of Resistance.”
Because Iran and Israel share no common border—and because Israel possesses overwhelming conventional military superiority—Iran has historically pursued its objectives through asymmetric warfare rather than direct interstate conflict.
Over several decades, Tehran developed an extensive network of allied non-state armed groups, including Hezbollah in Lebanon, Hamas and Palestinian Islamic Jihad in Gaza, the Houthi movement in Yemen, and numerous Shi’a militias operating across Iraq and Syria.
Collectively, these organizations formed a strategic deterrence architecture designed to surround Israel with multiple active fronts while simultaneously expanding Iranian regional influence.

The Obama Administration’s Diplomatic Counter-Strategy: The JCPOA
Iran’s expanding nuclear programme significantly increased international concerns regarding nuclear proliferation and regional stability.
In response, the administration of U.S. President Barack Obama pursued a diplomatic strategy intended to constrain Iran’s nuclear ambitions while avoiding another major Middle Eastern war.
The result was the Joint Comprehensive Plan of Action (JCPOA), signed in July 2015 by Iran, China, France, Germany, Russia, the United Kingdom, the United States, and the European Union.
The agreement represented a sophisticated arms-control framework rather than a normalization of relations.
In exchange for phased sanctions relief, Iran accepted strict limitations on its nuclear programme, including:
• Uranium enrichment capped at 3.67%
• Reduction of enriched uranium stockpiles by approximately 98%
• Significant cuts in operational centrifuges
• Comprehensive inspections by the International Atomic Energy Agency (IAEA)
From a non-proliferation perspective, the agreement extended Iran’s estimated nuclear breakout time from only several weeks to approximately one year.
However, the JCPOA also contained significant weaknesses.
Critics—particularly in Israel and among many U.S. Republicans—argued that the agreement merely postponed rather than solved the nuclear issue through its sunset clauses.
Furthermore, it deliberately excluded two crucial components of Iranian power projection:
• the ballistic missile programme;
• Iranian support for regional proxy organizations.
⸻
The Collapse of the JCPOA
In May 2018, President Donald Trump withdrew the United States from the agreement and reinstated comprehensive economic sanctions under the “Maximum Pressure” campaign.
Iran gradually responded by abandoning many of its commitments:
• increasing uranium enrichment;
• deploying more advanced centrifuges;
• limiting IAEA inspections.
As a result, the diplomatic architecture designed to prevent nuclear escalation steadily eroded.
⸻
From Shadow War to Direct Military Confrontation
The collapse of the JCPOA, combined with the regional upheaval following Hamas’ attacks on 7 October 2023, fundamentally transformed the strategic balance between Israel and Iran.
The long-standing pattern of covert operations and proxy warfare has increasingly evolved into direct military confrontation.
Israel now follows a doctrine aimed at degrading Iranian military capabilities before they become existential threats.
This strategy combines:
• cyber operations;
• precision air strikes;
• intelligence-led targeted killings;
• sabotage operations;
• attacks on missile production sites;
• strikes against nuclear-related facilities;
• operations targeting Islamic Revolutionary Guard Corps (IRGC) command structures.
Rather than focusing exclusively on Iran’s proxy organizations, Israeli strategy increasingly seeks to impose direct costs on the Iranian state itself.

The American Role
The United States has simultaneously expanded its role beyond that of a traditional security guarantor.
Washington continues to provide:
• intelligence sharing;
• missile defence cooperation;
• naval deployments;
• logistical support;
• extensive economic sanctions.
Together, these measures constitute a comprehensive strategy of military, economic, and diplomatic containment designed to limit Iran’s ability to project power across the Middle East.
Despite these efforts, the strategic competition remains unresolved.
Iran retains:
• a substantial missile arsenal;
• significant regional influence through surviving proxy networks;
• a nuclear programme whose theoretical breakout timeline continues to shorten.
The region has therefore entered a period of heightened deterrence instability in which limited military exchanges could rapidly escalate into broader interstate conflict.

Possible Paths Toward De-escalation
Although the current strategic environment appears increasingly confrontational, several realistic pathways toward de-escalation remain possible.
1. A New Nuclear Agreement
The first scenario involves negotiating a broader successor to the JCPOA.
Such an agreement would likely require:
• longer or permanent restrictions on uranium enrichment;
• strengthened IAEA inspection powers;
• limits on ballistic missile development;
• negotiated constraints on Iranian support for proxy organizations.
In return, Tehran would seek:
• phased sanctions relief;
• reintegration into international financial markets;
• security guarantees against external attempts at regime change.
Although politically difficult, this remains the most comprehensive institutional mechanism for restoring long-term strategic stability.

2. Managed Deterrence
A second possibility involves maintaining mutual deterrence without formal diplomatic normalization.
Under this model, Iran and Israel would remain strategic adversaries while tacitly respecting mutually understood limits on military operations.
Third-party mediators—including Oman, Qatar, Switzerland, and European governments—could facilitate indirect communication designed to prevent accidental escalation following cross-border strikes or proxy attacks.
History shows that such crisis-management mechanisms can significantly reduce escalation risks even in the absence of formal peace agreements.
⸻
3. Regional Security Integration
A third scenario envisions broader regional diplomacy.
Continued normalization between Israel and several Arab states—combined with gradual Saudi-Iranian rapprochement facilitated by China or regional organizations—could alter Tehran’s strategic calculations.
Greater economic and political interdependence would increase the costs of sustained confrontation while encouraging greater strategic restraint.
⸻
4. Political Change Inside Iran
The final scenario centers on domestic political transformation.
Leadership succession, institutional reform, or broader changes within the Iranian political elite could eventually produce a recalibration of foreign policy priorities.
Rather than abandoning opposition to Israel altogether, a future Iranian leadership might prioritize:
• economic recovery;
• domestic legitimacy;
• international reintegration;
• regional stability.
While highly uncertain, history demonstrates that major leadership transitions can profoundly reshape a state’s external strategic behaviour.
⸻
Conclusion
The strategic rivalry between Iran and Israel has entered a new and considerably more dangerous phase.
The collapse of the JCPOA, the erosion of diplomatic safeguards, and the growing shift from proxy warfare toward direct military confrontation have significantly increased the risks of regional escalation.
Ultimately, sustainable de-escalation will depend upon restoring credible deterrence while rebuilding diplomatic mechanisms capable of managing crises before they evolve into open interstate war.
Without such safeguards, the gradual disappearance of informal restraints risks transforming periodic military exchanges into a prolonged regional conflict with profound consequences for both Middle Eastern and global security.
