Introduction of Israel and Iran war conflict
The main event in the conflict between Israel and Iran in 1979 which brought forth a secret alliance based on unity, policy ambition, region and ideological rivalry. Here is a description of its history and major stories.https://edition.cnn.com/world/live-news/israel-iran-attacks-06-17-25-intl-hnk
The conflict between Israel and Iran is divided into two phases, the first phase is before 1779 and the second phase is after 1979 which is given as following:

Phase I – Before 1979: Strategic Alliance (Alliance of Israel and Iran):
At this time the king of Iran was Mohammad Shah who had western affinities, so Israel supplied Iran with assistance in agriculture, technology, weapons and also taught them how to drive. Iran changed its oil export to Israel. The symmetrical harmony between Israel and Iran was that the intelligence agencies of both countries (SAVAK and Mossad) were working together.

Phase II – After 1979: Islamic Revolution & Ideological Rift :
In this phase the Shah’s regime was removed due to the Islamic Revolution and the establishment of the fundamentalist Shia Islamic Republic under the leadership of Ayatollah Khomeini fundamentally changed everything, this separation (Shia) questioned Israel’s consent, due to which Israel strongly opposed it, which also led to the breakdown of mutual relations between the two countries. It reached a point where Ayatollah Khomeini gave the title of “Big Devil” to the United States and “Little Devil”, “Cancer” to Israel.

Timeline of Escalation (Post-1979) in detail below:
1980s: Proxy Wars Begin between Israel and Iran:
Iran created terrorist organizations for the war against Israel and also provided financial support, weapons and weapons training.
In 1982 : After Israel invaded Lebanon, Iran formed Hezbollah (Lebanon), an offensive group, in collaboration with Lebanese Shia Muslims. Iran trained and supported the group in arms. Israel saw the group as the most dangerous offensive force on its northern border.
In 1983: The Iranian-run Hezbollah attacked Israeli forces inside their Lebanese headquarters with suicide bombings, causing the Israeli army to withdraw from most of Lebanon.
Hamas and Palestinian Islamic Jihad (Gaza): Iran provided Gaza with weapons and Iranian-Iranian relations, while Gaza and Iran relations flourished during the Syrian war.

1990s: Attacks Abroad:
In 1992, Israel accused Iran and Hezbollah of suicide bombings on the Israeli embassy in Buenos Aires and on a Jewish center in 1994, killing several people. But Iran and Hezbollah denied responsibility.
2000s: Nuclear Tensions Rise between Israel and Iran:
Iran’s announcement in 2002 of its secret uranium reserves led Israel to worry that Iran was trying to build a nuclear bomb in violation of the Non-Proliferation Treaty, prompting Israel to call on the United States to take action against the Islamic Republic.
In 2006, after a month-long war between Israel and Hezbollah inside Lebanon, Israel retreated. Hezbollah had high-level weapons from Iran, due to which Israel was able to completely crush this organization.
In 2009, In a speech of Iranian Supreme Leader Ayatollah Ali Khamenei described Israel as “a dangerous and malignant cancer”.
In 2010, a virus created in the United States and Israel named – “Stuxnet“, was used to attack the uranium facility at Iran’s nuclear site. It was the first publicly announced cyber attack.https://www.thehindu.com/news/international/israel-iran-conflict-missile-strikes-tehran-khamenei-netanyahu-june-17-2025-live-updates/article69703297.ece

2010s: Covert Operation between Israel and Iran:
In 2012, Iranian nuclear scientist Mustafa Ahmadi-Roshan was killed by a biker after his car blew up, with an Iranian official blaming Israel for it.
In 2020, Iran’s General Commander Qassem Soleimani was killed by an American bomb.

2020s: Open Hostility:
In 2021, The mystery of the assassination of Mohsen Fakhrizadeh, the mastermind of a nuclear weapons program developed by Iran, is attributed to Israel.
In 2022, Under the “Jerusalem Declaration“, the President of Japan and the Minister of State of Israel pledged that they would make every effort to prevent Iran from becoming a nuclear power.
In 2024, Attacks on Iranian embassies killed many people. Israel gave details of the first attack on Iran and named these attacks to destroy Iran’s nuclear program – “Rising Lion“. In this attack, Iran’s media house has reported the death of Tehran’s Revolutionary Guards commander Hossein Skate and nuclear scientists Fereydoon Abbasi-Davani and Mohammad Mehdi Tehrani.

Conclusion
The story of Israel and Iran is a long and complex one from alliance to enmity. The Islamic Revolution of 1979 dramatically changed the relationship between the two countries—where previously the two nations were overt and covert partners, they now became bitter adversaries.
After the Islamic Revolution, Iran challenged Israel’s credibility and waged a powerful war against Israel through radical groups like Hezbollah and Hamas. Israel, in response, also tried to hold back on nuclear weapons.
The events of the war—such as the “Rising Lion” attack, the nuclear bomb assassinations, and missile/drone attacks—show that the conflict between the two countries has now become open and dangerous. This conflict is not just between two countries, but has also become a serious challenge to regional and global stability.
The essence of this entire conflict is that the risk of a Syrian military confrontation has increased more than ever.
