Dr. Sebastian Gorka appeared on "Fox and Friends" today to discuss how we can win the propaganda battle against radical Islam and counter the recruitment tools used by terror groups like ISIS.

Gorka, author of "Defeating Jihad: The Winnable War," pointed out that ISIS, in particular, has a huge range of media products, from incredibly active social media accounts to the English-language magazine "Dabiq."

"They're crushing it on social media," Gorka said. "They are basically providing very short enticing messages of why to be a holy warrior, how you have to attack the infidel."

Gorka asserted that we need to combat this propaganda by fighting fire with fire.

"We have to start fighting the war of ideas. We're not doing it," Gorka said. "This is a war of the mind. We have to stop people wanting to become jihadis."

He explained that we should use a similar strategy to what we implemented during the Cold War.

"We have to have counter-propaganda. We haven't really started. We have to push back in that domain."
