“I would like to see a declaration of war against ISIS,” Rivera said. “I would like to see ISIS removed by any means necessary, including - and this is probably the most controversial thing I’m going to say this morning - the rehabilitation of the Syrian dictator Bashar al-Assad and his Shiite forces who have successfully kept them at bay."

"[ISIS] only controls one third of Syria,” Rivera said, adding that Assad is the enemy of our enemy, therefore, our friend.

“I want us to rehabilitate the dictator in Damascus. I think he can be forced to make his own government more inclusive, head to some kind of settlement of the Syrian Civil War and the Syrian army, a fine army, [and] join with American air power and our Iraqi allies."

"All must make common cause against this dreadful threat to civilization.”
