According to Christian Examiner:
The terror attack that took place in San Bernardino, Calif., last week was a new evolution of terrorism, President Barack Obama said in an address to the nation on Sunday.
Because the attack was not an international operation, the president said, it was much harder to detect than “complex, multifaceted attacks like 9/11,” in spite of the fact that the terrorists, Syed Rizwan Farook, 28, and Tashfeen Malik, 27, had stockpiled a large amount of weapons, ammunition and pipe bombs.
While Obama said the victims of the attack were “brutally murdered and injured by one of their coworkers and his wife,” he did define the attack as an act of terrorism. However, stopped short of saying the attackers had been directed from terror groups overseas. He also said there was no hint of a “broader conspiracy” either.
