He's technically correct according to some schools of international politics.

But he's saying this to casually connect Iran to a declaration of war on Israel. In all that blab he casually infers Hezbollah is an Iranian military unit and it declared war on October 8th. Which creates the question of a casus belli against Iran.

This is a propaganda technique where stuff like this is mentioned in passing by a bunch of different people. Our full attention is on the idea that he's delegitimizing the surrounding countries. But that other bit slips past and if we hear something over and over without questioning it we can actually internalize it.

So that's kind of scary to think about.
