Until 1979, the two countries enjoyed friendly relations, with Iran being one of the first countries to recognize Israel in 1950.
However, after the Islamic Revolution, Iran began viewing the US as the “Great Satan” and Israel as the “Little Satan,” leading to a complete severance of ties between them.
Israel sees the hatred of Iran as stemming from the Tehran regime’s ambition to spread ideological revolution and Islamic ideology throughout the Middle East.
The rivalry became worse when Iran started funding armed organizations such as the Shiite Hezbollah in Lebanon and the Sunni Hamas in Gaza.
