This has nothing to do with the ruling Mullahs. Its to do with Iran advancing in nuclear technology. Funny how you like western politicians always point to the Mullahs when its the people being targeted by the sanctions and the scientists being killed, the Mullahs aren't affected. Oh and FYI my glasses are realistic *tries to remember the last time Iran attacked another country since the revolution* ermmmm NEVER. The conclusion? The Mullahs, despite their craziness are far peaceful and tolerant than the likes of NATO/US---fact that no amount of BS and warmongering rhetoric can change.  

 And before you say OMG look at their human rights abuse, I suggest you look at the human rights records of every single nuclear armed state today and the 'moderates' in the region. Meh.
You're ranting about several different issues here. Breaking it down:
1/ Teh Mullahs (may the fleas of a thousand camels infest their beards): Unfortunately, this does have everything to do with the ruling mullahs, since it's the ruling mullahs who get to call the shots in Iran. Denying this is head in the sand material.
2/ Nuclear technology: Not necessarily a bad thing, or at least it can be argued that way. However, the uses to which it will be put are important.
3/ Sanctions: Yes, I know they always have less direct effect on ruling classes, who can insulate themselves to a large extent. However, sanctions are intended to be a less destructive (compared to military action) means of exerting pressure, by making the ruling classes less popular within their own country. IOW, the hope is that sanctions will be less harmful to the general population.
4/ Assassinations of scientists: I agree this is not good.
5/ Iran attacking other countries: No, Iran has not engaged in outright and direct military action using its state's armed forces. However, it still has to be said that Iran has definitely been 
involved in attacking other countries.
6/ Mullahs being peaceful and tolerant: Yeah, sure. Just don't mention the last "Green Revolution", or the calls for the extermination of Israel, or the support for groups who want that result.
And don't try to deflect this into a "Fuck Israel" rant. The point is not whether Israel rocks or not. The point is "What does Iran want nuclear weapons for?".
7/ Human rights issues: I agree that most states in the region have human rights records that vary from bad to worse. That still has nothing to do with the central issue here.
The central issue, IMO, is whether or not a nuclear-armed Iran will be a good thing.
Oh and fuck Chelsea. They're the reason why I'm ranting right now. GRRRRRRRRRRRRRRRRRR :@
Bomb them. It's good for freedom and democracy.
