We have recently had an attack. It is quite possible that those kind of elements may be planning an attack on a tourist resort during Christmas. It is a scary thought. But the warnings are out there. The possibility of a holiday strike is there, and we should maintain general vigilance at all times.
There are warnings from Islamic clerics: do not participate in the infidels' festivities, do not wish them holiday greetings, do not endorse or participate in any manner what Muslim hardliners see as celebrations of infidelity and the rejection of Allah. This way of thinking is being reemphasized among Salafist communities and it instills a contempt and hatred for non-Muslims particularly on the occasions of their holidays and could become the rationalization for an attack during the Christmas holidays.
The Jihadists have an eye for the grand symbol, and this could conceivably take the form of a strike around Christmas.
