The United States became painfully aware of the threat posed by global jihadism after the terror attacks of September 11, 2001. Until that day, Iranian-backed terrorist networks, such as Hezbollah, were responsible for killing more American citizens than al-Qaeda. In the years since, the balance has been gradually tilting back towards Iran. In the words of former U.S. Deputy Secretary of State Richard Armitage, al-Qaeda may be the 'B' team of international terrorism, but Hezbollah is the 'A' team. Indeed, Iran's Khomeinists began their war on the U.S. and other democracies years before Osama bin Laden began his jihad.
