At least 22 people were killed and 59 were injured when a suspected suicide bomber detonated a device at an Ariana Grande concert Monday night in Manchester, U.K.
British authorities on Tuesday identified the suicide bomber as 22-year-old Salman Abedi.
ISIS has claimed that Abedi was "a soldier of the caliphate," but Director of National Intelligence Dan Coats said that the U.S. had not yet verified that the terror group was responsible.
On "Happening Now" today, Ric Grenell said radical Islamic terror keeps happening because of "religious fanaticism" and the idea that martyrdom will be rewarded.
He pointed out that President Trump, in his speech to dozens of leaders from Muslim countries, confronted them with the fact that this type of terrorism is a religious issue.
"He said, 'We have to make very clear to those who are suicide bombers, to those who are doing terrorism, that they cannot be rewarded for this, that they will be condemned,'" Grenell said. "Confronting this idea that you are not going to be rewarded, but you are actually going to get condemned to hell cuts into why they are doing this."
He said Trump bringing up this religious angle could be a "game changer" that could transform the messaging the State Department delivers to Muslim and Arab leaders.
"We should begin to talk about why terrorists are doing this and flip the script," Grenell said. "Let's show them that if you do this ... the religious consequences are going to be the opposite. They're going to be condemned to hell."
