Report: ISIS Training 'Hundreds' of Fighters to Attack Europe in Waves

As Europe reels from this week's terror attacks in Brussels, Belgium, the civilized world continues to ask how the ISIS terror army can be defeated and whether enough is being done. 

In a special "War Stories" presentation, Lt. Col. Oliver North (Ret.) and former Navy SEAL Leif Babin went deep inside the confrontation between moderate Muslims and the Islamic State’s extremist ideology.

In an exclusive interview, the Chairman of the Joint Chiefs of Staff, General Joseph Dunford talked with Col. North about what's being done to combat ISIS. 

He was asked whether tens of thousands of U.S. troops will be needed on the ground, particularly to stop ISIS' black market sales of oil. 

"My perspective is that long-term success is gonna require effective indigenous forces on the ground for long-term stability, but I do believe that unique US capabilities are gonna be equally important for us to be successful," the general answered. 


Gen. Dunford addressed whether the United States has real allies in the Middle East, while Rep. Martha McSally called on Turkey to do more.


North asked how the situation is different from what U.S. troops were facing during the Iraq War. 

"Today we're probably dealing with a more virulent strain of extremism in the form of [ISIS]," the general said, adding that ISIS can be defeated and "will be defeated."

Watch clips of the interview above and catch the full airing of "War Stories: Fighting ISIS" on Saturday at 5:00pm ET and Sunday at 3:00pm and 11:00pm ET on Fox News Channel.

You'll also hear from San Bernardino Chief of Police Jarrod Burguan, U.S. Rep. Martha McSally (R-AZ) - a retired U.S. Air Force Colonel who sits on the Homeland Security and Armed Services Committee - and many other terrorism and homeland security.experts.
