Ron Dermer, Israeli ambassador to the United States, sounded off on militant Islam in a “Kelly File” special.

“The most important thing in fighting [militant Islam] is understanding that all these groups that people think may have this or that local grievance – they’re all connected, they’re all fired by the same fanaticism,” he said.

Dermer explained that while these terror groups sometimes fight each other, they all hate Jewish people, Christians and America.

Martha MacCallum asked Dermer his advice on making the world safer.

“Identify the danger, and then you have to take action to meet it,” Dermer said, calling for effective policing, intelligence and laws. He also said waging a moral battle is important.

“The single most important thing in fighting terrorism is moral clarity,” he said. “You have to take a stand against terrorists.”
