There has been repeated offers made from united Iranian factions to give mullahs amnesty if they step aside. Its not in the nature of these fundamentalist vampires to do so. They dont consider themselves guests. And with the shrinking world of victims, they have nowhere to go but to get wiped out. Something big will happen in June, hopefully, peacefully.
As Rafsanjani once said
"Mah neyoomadem enja khe basyeh mehmooneh, mah omadem khe beboonem.'
We didn't come here for dinner or get-together, we came to stay.
