lol Iran is a regime, but that's and at that point seems ridiculous ...
What makes Iran a regime? tell me.
The fact that the Islamic Revolution was taken over by Dogmatic old men who could rally crowds, their funding came from the USA. It's a regime, it's not perfect, but it's getting somewhere.
Other reasons include funding pro-Mugabe radio in Zimbabwe, not being very nice to Kurds... etc. etc.
Islamic Republic or a regime, call it what you want, it's a bit shitty but that's not our problem. Every country has an indegenous democracy movement.
