Khomeini was the surpeme leader. Masoud Pezeshkian is the president and very much alive. For once, the abbreviation DYOR means something on this board. It's not hard to google a fact if you are going to spout it.
I think you will find the Iranian president is alive and well (as well as someone with a red dot on every location he is in probably is, I imagine), and has been in place since 2024.
