What do the following countries have in common? Argentina, Australia, Cyprus, France, Germany, Greece, Israel, Kenya, Kuwait, Nigeria, Pakistan, Sweden, Thailand, the United Kingdom, and the United States. The answer is that all have been on the receiving end of Iranian terrorism, either directly or through a Tehran-backed proxy, such as Hezbollah.

Think about that list. What possible interest could the ayatollahs have had in, say, Buenos Aires, which lies 8,500 miles from Tehran? In 1994, a militant drove an explosives-laden van into a Jewish community center, killing 85 people and injuring more than 300. Argentine prosecutors followed the trail back to Iranian state officials.
