You might want to take a look at the U. S. State Department’s “Country Reports on Terrorism”. Here’s the first paragraph of Chapter 1, “Strategic Assessment”:
Although terrorist attacks and fatalities from terrorism declined globally for the second year in a row in 2016, terrorist groups continued to exploit ungoverned territory and ongoing conflict to expand their reach, and to direct and inspire attacks around the world. The Islamic State of Iraq and Syria (ISIS) remained the most potent terrorist threat to global security, with eight recognized branches and numerous undeclared networks operating beyond the group’s core concentration in Iraq and Syria. Al-Qa’ida (AQ) and its regional affiliates remained a threat to the U.S. homeland and our interests abroad despite counterterrorism pressure by U.S. partners and increased international efforts to counter violent Islamist ideology and messaging. Terrorist groups supported by Iran – most prominently Hizballah – continued to threaten U.S. allies and interests even in the face of U.S.-led intensification of financial sanctions and law enforcement.
Africa as usual is probably in the worst shape but it will, of course, continue to be ignored by us. African terrorism just isn’t that much of a threat to us.
What is the roadblock, exactly, which precludes us from identifying, and eliminating, members of the Salafi sect? Is it still that it may hold sway over the House of Saud? And thereby disrupt world oil supplies? Hardly. I suspect that among Muslims, they inspire realistic fear.
Much as the Klan did in the thirties. It’ll take real balls to break them.
Worldwide there are tens of millions of Salafists. There are 4 million in KSA alone (about a quarter of the population).
Most imams in most Western countries were born in KSA and are likely to be Salafists.
