9/11 in my opinion was a clear declaration of the Islamist war against America. Since that time we have witnessed Islamist attacks, most recently in Orlando and San Bernardino, but also at Fort Hood (against the American military!), the Boston Marathon, and the Seattle Jewish Federation. Those commentators who seek to minimize the continuing danger of more Islamist attacks by citing other non-Muslim mass murders are being, I believe, disingenuous, as one cannot win one war by saying we are losing another war. That is surrender.
Around the world Islamists have murdered in Paris, Brussels, Madrid, London and throughout Scandanavia and Germany where the attacks take the form of sexual assault against non-Muslim women. In fact all over the world, where Muslims live with non-Muslims, there are constant attacks in places as diverse as the Philippines, Nigeria, Russia, and of course, Israel.
