Many in Iran believe he thinks of nothing but a strict victory, as that is the only way that he can remain in power and will not be sentenced to prison. This requires him to postpone any peace negotiation to after the US election, in the hope that maybe Trump will win and US will help him more effective. This is perhaps why he refuses to accept any peace agreement, as reaching to an agreement will be a shot in the foot, as that would help Harris campaign in front of Trump's. So all that he does is to buy time, and to wait in the hope that something good will happen. [This is what a politician proposed several weeks before, so it does not include the incidents that happened through the past few weeks, some of them being justifiable only as a matter of fighting for remaining in Power till US election, and others fighting for existence of Israel altogether.]
