Why Iran Israel war started, What is the original issue of the Iran & Israel War?

Hello, We are All Vision India, Hope you are well

The current direct conflict between Iran and Israel, which has seen direct missile strikes and counter-strikes, is a significant escalation of a long-standing "shadow war" or "proxy conflict" that has been ongoing for decades.

The Original Issue and Historical Roots:

The fundamental issue between Iran and Israel stems from the 1979 Islamic Revolution in Iran. Prior to this, Iran under the Shah and Israel had relatively cordial relations, even acting as strategic partners against common regional adversaries. However, the Islamic Revolution brought a new theocratic regime to power in Iran that adopted a vehemently anti-Israel stance.

Key aspects of this ideological shift and the origins of the conflict include:

• Non-recognition of Israel: The new Iranian government immediately withdrew recognition of Israel as a state, referring to it as the "Zionist regime" and "occupied Palestine."
• Support for Palestinian causes and anti-Israel groups: Iran became a staunch supporter of Palestinian groups like Hamas and Palestinian Islamic Jihad, and Lebanese Shia militias like Hezbollah, which Israel views as terrorist organizations. This support is a core component of Iran's "Axis of Resistance" aimed at opposing US and Israeli interests in the region.
• Ideological opposition: The Islamic Republic of Iran is founded on principles that are fundamentally opposed to the existence of a Jewish state in the region.
• Regional Dominance: Both Iran and Israel have competing interests and aspirations for regional influence, leading to proxy conflicts in various theaters like Syria and Yemen.

Why the "War" Escalated Recently (2024-2025):

While the underlying tensions are long-standing, the direct escalation into what is now being referred to as the "Iran-Israel War" or "Iran-Israel Conflict 2024-2025" was triggered by a series of events, primarily:

• Iran's Nuclear Program: Israel views a nuclear-armed Iran as an existential threat. Iran has been enriching uranium to near-weapons-grade levels, and the International Atomic Energy Agency (IAEA) has recently declared Iran non-compliant with its nuclear non-proliferation obligations. This has pushed Israel to act more forcefully to dismantle Iran's nuclear capabilities.
• Hamas's October 7, 2023, attack on Israel and the subsequent Gaza War: This attack intensified regional tensions and led to a crushing Israeli response that has significantly weakened Iran's proxy groups, particularly Hamas and Hezbollah. This perceived weakening of Iran's "Axis of Resistance" may have created a strategic window for Israel to directly target Iran.
• Assassinations and Direct Strikes: Israel has been carrying out covert attacks, cyberattacks, and assassinations of Iranian nuclear scientists and military officials for years. The recent escalation saw more overt and direct strikes, such as Israel's bombing of an Iranian consulate complex in Damascus, Syria, on April 1, 2024, which killed senior Iranian officials.
• Retaliation and Counter-retaliation: Iran retaliated for the Damascus strike with missile and drone attacks on Israel in April 2024, which in turn led to further Israeli retaliatory strikes against Iranian nuclear and military sites in June 2025.

In essence, the current direct conflict is the culmination of decades of mutual hostility, a "shadow war" fought through proxies, and an increasingly urgent Israeli concern about Iran's nuclear program, all brought to a head by recent events in the broader Middle East.
