Iran's long history of terror and aggression

Iran's recent acts of aggression against the U.S. and its allies follows a long history of terror by the state, including a recent modernization of tactics in the form of cyber hacks and disinformation campaigns.

This is the latest provocation by Iran -- the second-largest country in the Middle East -- as it prepares to negotiate with the U.S. and other world leaders about the 2015 Iran nuclear deal.    Since it became the Islamic Republic of Iran in 1979, Iran has a long history of using terror and other acts of aggression to achieve its political objectives.  For 42 years, it has been designated by the U.S. and other world powers as the leading state sponsor of terrorism around the globe. It has backed other terrorist organizations — such as the Taliban and Hezbollah — to further its goals.
