3 top Deadliest Terrorist groups:

1. The Islamic State of Iraq and the Levant:

3. Islamic Revolutionary Guard Corps-Quds Force:

2. Boko Haram

It takes a special kind of terrorist organization to force the world’s most powerful and professional military into action halfway around the globe. The Islamic State of Iraq and the Levant is exactly this type of organization: strong enough to rout several divisions of a national army, and rich enough to sustain their operations at an impressive pace.

Boko Haram has been menacing Nigeria’s northern communities for years. Public reports state that the organization was founded in 2002, but it’s activities only reached global spotlight in 2009, when Boko Haram’s new leader, Abubakr Shekau, launched what can only be described as an insurgency against the Nigerian government using nothing but terrorist tactics.

This highly-secretive branch of the Islamic Republic is incredibly effective at what it does: connect with, maintain and support terrorist groups in the region that will enhance Iran’s regional posture and keep its enemies off balance. And that is why the Quds Force is so dangerous.
