I agree some Jewish extremists exploit Hamas extremism but the primary group responsible for Hamas are Palestinian extremists themselves.
Around half a century ago Greece had a rightwing dicatorship. This was supported by the US which sometimes uses the CIA and state department to support dictatorships over democracy in other countries because they see it in their own national interests. Some Greeks to this day have never forgiven the US for this (typically the far left). They ignore that a large number of Greeks of that era supported the Junta purely because they were anti-communist (I am anti-communist Greek but support democracy). The US was morally complicit in the junta yes but it would never have happened if a large segment of Greeks themselves hadn’t support it.
This lack of honest reflection of one’s own actions is why the ranian government have ended up extreme. They Ayatollah et al continue to blame the US for everything wrong with their nation rather than honestly argue they are mostly responsible for their own mistakes. Their government use exaggerated grievance of America as a way to distract attention away from their own incompetence.
It’s true many Jews want to get rid of Palestinians from the region. A segment even want to get rid of all minorities for Israel… but expect their own minorities rights respected in other states. However this sort of behavior isn’t limited to Israel. It’s practically an international sport for all groups to cry persecution when a minority in someone else’s homeland then change tunes when it comes to their own homelands where they ethnic cleansed minorities and later try to keep out migrants. (which is true of Greece as well)
The solution to this problem is honest discussion of how to resolve the matter of homeland versus globalization in a manner fair for all… not singling out any nation in particular for being to blame. This inconsistent behavior is not a new thing. It’s as old human civilization.
