Muslim Terrorism has become as much of a Christmas tradition for Christians in the West, as it already was for Christians in the Muslim world, where Somali Muslim gunmen attacked a Christmas party at an African Union base.
A Somali Muslim attempted to bring terrorism into the United States by bombing a Christmas tree lighting ceremony in Portland in 2010. Mohamed Osman Mohamud (twice the Mohammed for twice the mayhem) had a simple goal, "I want whoever is attending that event to leave, to leave dead or injured."
