> Iran has never attacked Israel unless attacked first

Iran was involved in attacks against Israel and Israeli towns in the 1980s and 1990s by their mercenaries in Hezbollah and direct IRGC presence in Lebanon. This happened even when Israel supported Iran during the Iraq-Iran war, so this is strictly not true

Other incidents were the Iranian bombings of the Israeli embassy in Argentine or the Jewish center there, and attempts on the London and Bangkok embassies

Furthermore financing of Hamas during the 1990s suicide campaign with the direct goal of derailing the peace process.

This is part of a long line of Iranian aggressive actions that have led them to being isolated and in a string of wars that greatly destroyed their already diminished economic power
