I suddenly recalled an article that I had read years ago in Iran-e Farda monthly that said according to some big deal western socialist socialogist*, totaliterian regimes do not open up or fall solely by internal pressure. It claimed that foreign pressure is always necessary to bent or break such systems. I've got to find more details about that theory but I don't even remember the name of that socialist socialogist. It will be an interesting study with conjunction to the current situation in Iran and all this Iranian analysts/intellectuals/bloggers such as Eyeranian who warn foreigners (read Americans) not to intervene in Iran's affairs.
