I think as long as Iran's government changes (I know from some friends in Iran that there are many highly educated people who have second thoughts about the current regime, not the fundamentalist nutjob that internation media likes to portray Iran as), and Iran backs out of the Middle East & get along with Israel (highly theoretical, but if Iran wants to balance out the Saudis, it would be possible), I think there would be great chances for Iran to grow as a nation.
Oh, if Iran ever wants to get friendly with Western Nations, go to Britian, not the US. They already destroyed your country once by destroying the parliamentary system of Iran back in the 50s.
