The Zionists and their supporters do not want a two state solution ever. Zionism is a fascist ideology. As such it needs the perpetual doublethink of "we are the greatest and superior to everyone else" like written in the Israel constitution as an Ethnostate for ethnic Jews while also constantly claiming "we are at the brink of extinction and need a brutal government to protect us, from all the other people".
The language, the demeanor and the actions of the mainstream Israel politics, media and culture are showing this to an extreme.
A one state solution would be the polar opposite, as it would not only rely on acknowledging that ethnic or any other supremacism is always wrong, but also the realization that not everyone is out to get you, if you stop murdering and oppressing people.
No one was interested in an escalation except Israel. Iran has repeatedly shown that they want to keep it at fighting through proxies. Syria is in shambles and Lebanon is struggling too. Jordan, Saudi Arabia and Egypt are all bought by the US.
Israel will stay at war, because that is what is keeping Bibi in power and now they have the opportunity for mass murder and land grabs like they haven't had in a long time.
The US could end all of this and if the US wasn't a genocidal colonial force on both parts of the political isle, it would do so.
