"Iran is the seed wart for much of the terrorism that goes on throughout the world and is also the model for radical theocratic regimes that preach their religious hate for all of the world to see."
Iran is a Shiite nation. Al Qaeda and most terrorists are Sunnis. Iran does sponsor Hezbollah, an adversary of Israel in Lebanon. This support confuses many Iranians. Israel and the United States are currently on a jihad against Shiites. A useful book about Iran is "A Honeymoon In Tehran". You might consider it to gain insight, although I gave it only a B-.
