The April terrorist attacks during the Boston Marathon killed and wounded scores of people. Machete-wielding thugs last week butchered a British soldier in full view of citizens on a London street. Simultaneously, in Sweden, a full five days of riots have seen burned cars, banks and schools, and assaulted citizens.
These attacks raise the uncomfortable question: "Why are we being attacked?"
A newly announced American policy to deal with such threats involves "addressing grievances and conflicts" that feed what is described as "extremism."
