There have been a number of incidents in the continental USA in the last 7 years that were intended to be terror attacks, but our government has twisted itself in pretzel shapes to avoid referring to them as such. "The Fort Hood Shooter was Workplace Violence" "The Boston Marathon bombing was a tragedy" "The San Bernadino massacre could be workplace violence". While sooner or later each incident is defined as terrorism the weasel words and pretzel twisting soon returns to the press conferences and speeches.
While this may be a kind of psychological warfare against terror organizations by denying them acknowledgment of their attacks it also serves to disquiet the citizens of my country. The attack in San Bernadino a few days ago was one more time that people who consider themselves to be devout Muslims have attacked targets within North America. Just last July there were several marines and a sailor shot in recruiting centers before fleeing in a running shoot out with police. An almost identical incident of shooting recruiters happened in June 2009. Later in 2009 the Fort Hood shooting took place. In 2013 the Tsarneyev brothers executed the Boston Marathon bombings and then engaged in a shoot out with police a few days later when they were spotted. In October of 2014 another Islamic man used a bladed weapon to hack four Police officers in New York before being shot dead. Then in December 2014 another Muslim gunman shot two NYC police execution style before taking his own life when cornered in the subway system. In May 2015 two Muslim men opened fire on the crowd at the 'Draw Mohamed' contest in Garland, Texas.
Terrorism has been with us for a long time, but it seems to me the pace of attacks has accelerated greatly over the last few years. One major attack in 2013, two attacks in late 2014 and now three attacks in 2015.
