The killing of Hamas’ main leader and chief negotiator, Ismail Haniyeh, while he was in Tehran, Iran is part of a cynical attempt by Israeli Prime Minister Benjamin Netanyahu to provoke an escalation of the conflict in the Middle East just so that he can stay in power. In this he can count on the complicity of Western imperialism, which allows him to remain in office as their main reliable ally in the region.
Liberal Zionists wanted his head ever since Yitzak Rabin was assassinated by a Israeli ultranationalist in 1995 and people accused Bibi of indirectly causing it, I wouldn't put too much stock into his opposition who have all been rug-pulled by Bibi for the ten thousandth time.
I don't know if Bibi wants to Ukraine Israel right now and declare military rule, that might just be the breaking point for the Tel-avivers. Idk maybe he's calling their bluff or he's just ironing up his legacy before he takes a long vacation to Miami with his family.
