The Council on American-Islamic Relations (CAIR) says the United States foreign policy has fueled the spate of extremism behind terror attacks around the world.

“Let’s not forget that some of our own foreign policy, as Americans, as the West, has fueled that extremism,” said a CAIR spokesman, Hussam Ayloush.

“When we support coup leaders in Egypt or other places, when we support dictatorships, oppressive regimes around the world that push people over the edge, then they become extremists, then they become terrorists. We are partly responsible,” he added.

“Terrorism is a global problem, not a Muslim problem. And the solution has to be global. Everyone has a role in it,” Ayloush said.

He made the remarks in an interview with CNN on Friday, two days after a couple armed with rifles and handguns attacked a center for people with developmental disabilities in San Bernardino, California, killing at least 14 people and wounding 21 others.

The assailants, Tashfeen Malik, 27, a native of Pakistan, and her husband, Syed Rizwan Farook, 28, were shot dead in a shootout with police hours after the massacre.

According to three US officials familiar with the investigation, on the day of the attack, Malik had pledged allegiance to Daesh (ISIL) in a Facebook post. It was however unclear whether the comments were posted by Malik herself or someone with access to her page.

The FBI also announced on Friday that it was treating the attack as an act of terrorism.

“The investigation so far has developed indications of radicalization by the killers, and of potential inspiration by foreign terrorist organizations,” the FBI director, James B. Comey, said at a news conference on Friday.

In the interview, Ayloush said American foreign policy has helped fuel the rage that drives Muslim radicals to kill in the name of their faith.

The Daesh (ISIL) Takfiri terrorist group declared in an online audio broadcast on Saturday that Farook and Malik were followers of the militants.

An English-language version of the broadcast was later released, calling the attackers "soldiers" of the terror group, rather than "followers.

US government sources, however, say the couple was inspired by Daesh, but there was no evidence the attack was directed by the militant group. The sources also ruled out that ISIL even knew who the couple was.
