One of them is currently more monied and has more support from imperialist governments, but they’ve both done horrible things to one another and ended millions of eachothers lives over millennia.
Israel is trying to put an end to it forever in the most effective way they can think of.
Violence.
Are you not aware that Iran supports Hamas? Are you pretending October 7 didn't happen?
I think you're being very selective in your reading of history.
Iran is trying to put an end to Israel through violence and colonialism. They support violent oppressive factions throughout the middle east.
There have been land for peace deals negotiated in the past, there's a willingness in Israel to make peace. But Iran gives support to violent factions like Hamas. Hamas has oppressively ruled over Gaza for over a decade and a half with the support of Iran.
Iran also supports the violent Houthi faction in Yemen which rules over a large part of that country (including the capital). The civil war there has been over 300,000 dead. They supported Assad's regime a brutally oppressive faction that took a civil war with over half a million dead before he was ousted from power.
How many people need to die in this insane theocratic authoritarian regime's goal to wipe Israel off the map before you'll consider the possibility that they might be a problem?
