Critics are weighing in about a new ISIS video that allegedly shows a captured Jordanian pilot  being burned alive in a cage. 

Fox Middle East and terrorism analyst Walid Phares told Jenna Lee on "Happening Now" that he believes this is a "game changer."

"The brutal killing by burning a prisoner of war, Lt. Muath al-Kaseasbeh, means that the norms of war do not apply anymore to ISIS," Phares said. "They have rejected any norms. Usually when you have a prisoner you don't kill them, you don't kill them in front of a camera, and you don't burn them." 

He remarked that Jordan and other Arab countries are going to look at this as a "very serious breach of international law." 

"They will have to change their strategies," Phares explained. "They know that if their pilots or military are captured, that they may encounter the same fate. That's why I presume that now it will be a game changer."

Peter Brookes, senior fellow at the Heritage Foundation added that "the international community needs to up their game."

"If we don't up our game, if the international community doesn't up their game against ISIS, this is the new normal and we'll see more of this," Brookes stated. "This group understands it has been able to operate with general impunity. It has a method to this terrible madness."

Phares agreed that more must be done against ISIS, but said the world needs "American leadership." Phares called on President Obama to move away from a strategy of "containing" ISIS and toward a real strategy to destroy them.
