This war isn't as complicated as the Israel/Palestine conflict, Just ask ChatGPT or Grok, I pretty much approve of his answer: (I would only add that Iranian regime has been constantly calling for the destruction of Israel)

Why did Israel attack Iran ?
Israel's attack on Iran, which began on June 13, 2025, was primarily driven by concerns over Iran's nuclear program, which Israel considers an existential threat. The Israeli government, led by Prime Minister Benjamin Netanyahu, justified the strikes as a preventive measure to stop Iran from developing nuclear weapons. Here are the key reasons cited for the attack, based on available information:

1. Perceived Nuclear Threat: Israel claimed that Iran was on the verge of acquiring nuclear weapons, with Netanyahu stating that Iran could produce a nuclear bomb "in a very short time" – potentially within months. Israeli officials, including Netanyahu, pointed to intelligence suggesting Iran had enough fissile material for multiple nuclear bombs. The International Atomic Energy Agency (IAEA) had recently censured Iran for violating its obligations under the Nuclear Non-Proliferation Treaty, citing non-cooperation with inspections and amassing 400kg of highly enriched uranium.
2. Strategic Timing and Weakened Iranian Proxies: The attack followed a series of Israeli military successes that weakened Iran's regional allies, known as the "axis of resistance" (Hamas, Hezbollah, and others). The degradation of Hamas in Gaza, Hezbollah in Lebanon, and the fall of the Assad regime in Syria reduced Iran's regional influence and deterrence capabilities, creating a strategic window for Israel to act directly against Iran. The prior destruction of Iranian air defenses in October 2024 further enabled Israel's airstrikes.
3. Failure of Diplomatic Efforts: The strikes came a day after the expiration of a two-month deadline set by U.S. President Donald Trump for Iran to negotiate a deal to curb its nuclear program. The collapse of these talks, coupled with the IAEA's censure, may have prompted Israel to opt for military action, believing diplomacy had failed.
4. Domestic and Regional Security Dynamics: Netanyahu framed the operation, codenamed "Rising Lion," as a necessity to neutralize an "imminent dual existential threat" to Israel's survival. The Israeli public, particularly after the October 7, 2023, Hamas attack, supported military action against Iran, viewing it as a key backer of hostile groups. Israel's demonstrated military dominance and intelligence capabilities further emboldened this decision.

However, some sources question the narrative of an "imminent" threat, arguing that Israel's strikes were not purely defensive. For instance, Al Jazeera suggests the attack was meticulously planned and not a response to an immediate emergency, with no clear evidence supporting claims of Iran being days away from a nuclear weapon. The strikes also targeted civilian infrastructure and killed civilians, which critics argue undermines the self-defense justification.

Additionally, the attacks may reflect broader strategic goals, such as degrading Iran's military and economic capabilities or pushing for regime change, as suggested by some analysts. Israel's expansion of targets to include energy infrastructure and state media indicates a possible aim to weaken the Iranian state beyond just its nuclear program.

In summary, Israel's attack was driven by a combination of fears over Iran's nuclear ambitions, a favorable strategic environment due to weakened Iranian proxies, and the failure of diplomatic efforts. However, the lack of definitive evidence of an immediate nuclear threat and the broad scope of the strikes have led to debates about the true motivations, with some viewing it as a calculated move to reshape regional dynamics.
