You are probably referring to the recent statements of Masoud Pezeshkian.

I consider them to be mostly political rhetoric, nothing has really changed. Iran has been in a hybrid war with NATO and Israel pretty much since the islamic revolution. This conflict does flare up every now and then, for example in June of this year, or at the beginning of 2020. So far though, it never turned into a total war, and I don’t see why it would be different this time.
