Blackmail?  Certainly a threat.  “Exclusive: Gulf states must not allow use of airspace against Iran, Iranian official says,” Reuters, 10-9-24.

“Iran warns of potential change in nuclear doctrine if Israel targets facilities,” Financial Times, 10-9-24.  Keep in mind that Israel’s actions do not force Iran to pursue nuclear weapons.  No country threatens Iran to need them.  Iran has all the oil and gas they need to be a modern and strong country.
