Sadly, the answer no one wants to hear is the war has to expand until it proves too costly for the US. Not necessarily WWIII, but Ansarallah/Iran has to start targeting oil refineries in the Arab comprador regimes. The Zionist entity is there to promote instability and sectarian divides within WANA and prevent the inevitable political unity of the peoples living there, but too much instability in such a vital geopolitical location is also a bad thing for empire.

As for the Zionist entity no longer existing, it is basically the 51st US state, so on some level, the Zionist entity can only cease to exist if the US is sufficiently weakened as a nation-state. This requires great powers, which right now would be Russia and China. As the US gets weaker, more states can also become key players in forcing the US's hand in giving up the Zionist entity.
