It will soon be the 20th Anniversary of September 11th - the day that Radical Islamists stole America's innocence and changed America forever! Do you know where the terrorists are now? Fortunately, today's guest, Robert Spencer, does. He's the 'canary in the coal mine' as Director of Jihad Watch, keeping tabs on the ongoing threat of global jihadists and keeping us informed, while most Americans have stopped watching. Most people have pushed memories of 9/11 down into the recesses of their mind because they find it too painful to remember. But, those who forget history are doomed to repeat it, and terrorists have not gone away, nor given up their plans to conquer the West. But why? Are jihadis dying for a fiction? Is there any sound historical evidence that the prophet of Islam actually existed or is the entire story of Muhammad fable or fiction? It is a question that few have thought—or dared—to ask. Virtually everyone, Muslim and non-Muslim alike, takes for granted that the prophet of Islam lived as a prophet, as well as a political and military leader, in seventh-century Arabia. But, this widely accepted story begins to crumble on close examination. Robert Spencer is a New York Times bestselling author, historian and Islam expert. His latest book, Did Muhammad Exist? An Inquiry into Islam's Obscure Origins, not only reveals the often-shocking contents of Islamic teachings about Muhammad, he also lays bare those teachings’ surprisingly shaky historical foundations. Are terrorists fighting for an illusion?
