And all this during Ramadan.
There is no way this can be explained away by saying "oh but those are radicalized Muslims, or it is the fault of foreign intervention." All the signs are there - change must come and is already coming to Islam in a spiritual way.
Spiritual forces from within and outside Islam will either modify or dispose of the religion as a fake. This in a very similar way as Maarten Luther, against all odds, broke the "radical" grip the Vatican Catholic Church had on many Christian countries in Europe during the 1500's.
One can foresee a scenario whereby Saudi Arabia, the present custodian of two holy mosques, could "implode" within 10 years. As will other countries in the area.
Change will not come without pain, but it will come and can not be stopped.
