1. Why Iran and Israel Hate Each Other: History of the Conflict Begins with an Unexpected Alliance
Many people assume Iran and Israel have always been enemies, but the reality is very different.
Before 1979, the two countries actually had friendly diplomatic and strategic relations. Iran even became one of the first Muslim-majority countries to recognize Israel in 1950.
During the Cold War period:
Iran and Israel shared intelligence cooperation.
Both countries viewed Arab nationalist governments as a common threat.
Economic and military cooperation existed between the two nations.
This alliance was part of Israel’s “periphery doctrine,” which aimed to build alliances with non-Arab states such as Iran and Turkey.
However, this relationship changed dramatically in 1979.
2. The 1979 Iranian Revolution: The Turning Point
The 1979 Islamic Revolution in Iran completely transformed Iran’s foreign policy and its relationship with Israel.
After the revolution:
The Shah of Iran was overthrown.
Ayatollah Khomeini established an Islamic Republic.
Iran adopted an anti-Israel ideological stance.
The new Iranian government declared Israel an illegitimate state and adopted the goal of opposing Israeli influence in the Middle East.
Diplomatic relations were immediately cut, and Israel’s embassy in Tehran was handed over to Palestinian representatives.
From that point onward, Iran and Israel became ideological rivals.
3. Ideological Differences Between Iran and Israel
Another major reason why Iran and Israel hate each other lies in their opposing political and ideological systems.
Iran’s Political Ideology
Iran is governed by an Islamic theocracy based on Shia Islamic principles.
The leadership often frames Israel as:
a Western ally in the Middle East
an illegitimate state occupying Palestinian territory
Iran also strongly supports Palestinian groups that oppose Israel.
Israel’s Political System
Israel is a democratic state with strong ties to Western countries such as the United States.
Israel views Iran as a major threat because:
Iran supports militant groups hostile to Israel.
Iran has developed ballistic missile programs.
Iran’s nuclear ambitions are seen as a security risk.
These ideological and security concerns deepen mutual hostility.
4. Iran’s Support for Anti-Israel Groups
One of the most important aspects of the Why Iran and Israel Hate Each Other: History of the Conflict debate is Iran’s support for regional militant organizations.
Iran has built a network of allies and proxy groups across the Middle East.
Some of the most significant include:
1. Hezbollah in Lebanon
Iran helped establish Hezbollah in the 1980s to oppose Israeli forces in Lebanon.
Hezbollah later became one of Israel’s most powerful adversaries.
2. Hamas in Gaza
Iran has also supported Hamas, a Palestinian militant organization involved in repeated conflicts with Israel.
3. Regional Militias
Iran has developed influence through various militias across:
Iraq
Syria
Yemen
These groups are often referred to as the “Axis of Resistance.”
Israel views this network as a major strategic threat.
5. The Iran–Israel Proxy War
For decades, Iran and Israel avoided direct war but fought indirectly through proxy conflicts across the Middle East.
This shadow conflict includes:
military support to opposing factions
intelligence operations
cyber warfare
sabotage operations
Since the 1980s, the two countries have engaged in a long-running proxy conflict affecting Lebanon, Syria, Iraq, and Gaza.
Examples include:
Israeli strikes on Iranian military bases in Syria
Iranian missile support to Hezbollah
cyber attacks targeting infrastructure
This proxy war has shaped Middle Eastern geopolitics for decades.
6. Nuclear Tensions Between Iran and Israel
One of the biggest modern factors in the conflict is Iran’s nuclear program.
Israel believes that Iran’s nuclear ambitions could threaten its survival.
Israeli leaders argue that preventing Iran from developing nuclear weapons is a top national security priority.
As a result:
Israel has allegedly conducted cyber attacks on Iranian nuclear facilities.
Iranian nuclear scientists have been targeted in assassinations.
Israel has launched airstrikes against suspected nuclear infrastructure.
In 2025, Israeli forces conducted major operations targeting Iranian nuclear facilities, further escalating tensions.
7. Direct Military Escalations (2024–2026)
In recent years, the conflict has escalated beyond proxy warfare.
For example:
Iran launched ballistic missile attacks against Israel in 2024 following regional tensions.
Israel conducted major strikes against Iranian military infrastructure.
In 2025, Israel targeted Iranian nuclear sites and military facilities.
By 2026, the conflict had intensified further, with large-scale airstrikes and missile exchanges raising fears of a wider regional war.
Recent reports show Iran-backed militias launching attacks across the region in response to joint operations targeting Iranian assets.
8. Geopolitical Rivalry in the Middle East
The conflict between Iran and Israel is also a struggle for regional influence.
Iran aims to expand its influence across the Middle East through political alliances and proxy groups.
Israel, meanwhile, seeks to prevent hostile forces from surrounding its borders.
This rivalry has shaped conflicts in:
Syria
Lebanon
Gaza
Iraq
As regional alliances shift, the Iran-Israel rivalry continues to influence Middle Eastern geopolitics.
9. Why the Conflict Matters Globally
The Why Iran and Israel Hate Each Other: History of the Conflict debate is not just about two countries.
The rivalry affects:
global oil markets
international diplomacy
global security
Major world powers, including the United States, Russia, and China, closely monitor developments in this conflict.
Escalation could trigger broader regional wars involving multiple countries.
10. Possible Future of Iran-Israel Relations
Experts believe the future of this conflict could take several paths.
1. Continued Proxy War
The most likely scenario is the continuation of indirect conflicts through regional militias.
2. Diplomatic Negotiations
International diplomacy could reduce tensions, although this remains uncertain.
3. Full-Scale War
If tensions continue to escalate, a direct military confrontation could occur, with serious consequences for global security.
