Numerous reasons have been given by different people for the 2026 Iran war, which began when the United States and Israel launched surprise airstrikes on Iran on 28 February 2026. The reasons are described as diverse, changing, and at times contradictory.

US and Israeli officials have framed it as a preemptive war of self-defense. They argue that diplomacy had failed to contain the unacceptable and potentially existential threats of Iran's nuclear program and ballistic missiles. They also argued the strikes were justified as a response to Iran's regional activities (support for proxy groups, attacks on shipping, etc.) and its violent suppression of domestic protests in January 2026. Critics have described it as a war of choice. Some analysts describe the war as a classic "security dilemma", where both sides saw the other's military buildup as threatening, making conflict increasingly likely even if neither side necessarily wanted full-scale war. Regional actors, like Saudi Arabia and the United Arab Emirates, share many of the US and Israel's war aims though differing on whether to pursue war or diplomacy.
