The only people wanting to continue this war are the U.S. and Israel (and maybe Saudi Arabia?) and even Trump is clearly looking for an off ramp.
This is most likely a way for Iran to tell Europe to do what they can to end this otherwise they will drag Europe into this mess as well.
The war is extremely bad for business for Saudi Arabia and has already cost them enormous amounts of money. It is causing damage to their oil refineries that will take years to repair.
The only person who gains anything out of this is Netanyahu and his friends. Everyone else loses, including the Israeli people.
