You should follow more seriously which usernames you're talking to. But as far as objective criteria, if a regime change happens I don't expect it to be subtle or debatable. Seeing the IRGC disbanded would be a pretty solid signal, though. Obviously it's not going to be done 100% from the air. The Iranian people will have to play a big role. I just hope they manage to seize initiative from Trump and Netanyahu as far as how their government is run. I do note that we've strayed a bit from the thesis of "Iran is so powerful Israel and the US have to gang up on it". :D
