Iran qnd Israel shared “warm ties” while the Shah was in power as a western puppet. His internal police was trained and worked together with Mossad and CIA to torture murder and dissappear tens of thousands of people.

The moment things changed is pretty straight forward. When the revolution kicked out the Western puppet. Unfortunately the revolutionary moment was seized by the theocrats who now also run an opressive regime.

You deliberately left out the paragraph right before that explaining all of this.

Motivated by the periphery doctrine, Imperial Iran and Israel had close relations, seeing Arab powers as a common threat. After the 1979 Islamic revolution, Iran cut off relations, but covert ties continued during the subsequent Iran–Iraq War. Iran trained and armed Hezbollah during Israel’s 1982 invasion of Lebanon, and continued to back Shia militias throughout the Israeli occupation of Southern Lebanon.[27] Even before 1979, Iranian Islamists had materially supported the Palestinians; after 1979 Iran attempted relations with the Palestine Liberation Organization, and later with Palestinian Islamic Jihad and Hamas. Israel fought a war with Hezbollah in 2006. Israel has fought several wars with Palestinians in and around the Gaza Strip: in 2008-2009, 2012, 2014, 2021 and 2023–2024. The 1982 Lebanon War and Israel–Hamas war have been the deadliest wars of the Arab–Israeli conflict.[28]
