The Iranians are pragmatic. Look beyond their relationship with the US. There are other state actors that Iran wants to remain in good relations with.

They understand that a defensive war is not the same as an offensive war. Besides, going on the offensive isn’t something they - as a regional power - have the firepower or diplomatic “street cred” for.

They are already painted as a so-called irrational actor. Doing something reckless will only prove their detractors right.

The other part to this is keeping the negotiation door open. The idea is to demonstrate to other state actors that they are cool headed & rational - even in wartime conditions.
