Though the Olympic Games have begun with all seemingly quiet on the terrorist front... threatening clouds have been gathering. ISIS has been advertising for Portuguese speakers and announcing 'Lone Wolf from anywhere in the world can move to Brazil now.' They even suggest how and where to attack, targeting Americans, British, French and Israeli visitors to Rio. Already about a dozen men have been arrested on suspicion of plotting attacks for a Brazilian Islamist militant group called the Defenders of Shariah. Today's guest, Dr. Sean McFate, is a terror-security analyst, who served as a paratrooper in the U.S. Army's Airborne Division, and is a professor at the National Defense University and at Georgetown University's School of Foreign Service. His newest book is Shadow War: A Tom Locke Novel. Besides Zika, polluted water, crime, political unrest, body parts washing up on the beach and more, we are waiting for the ISIS shoe to drop.
