Note that even in the heavily propagandized US the majority does not want to go to war with Iran, not even Trump's MAGA base wants that. I am pretty sure, the reality is that Israel has been treatening to use the Samson option in backchannel talks between the lines all the time. And all western so-called leaders haven fallen to the idea of sacrificing the Palestinians to avoid global disaster. But if history teaches us anything, it's not to negotiate with terrorists. Give an inch and they'll take a mile.
