Contemplation yes. Telegraphing a punch no. I think reducing Damascus and Tehran to rubble is first on the table Mecca is not. Unless you project a credible threat there is no way you can run a house to house winning strategy against Islam. They can produce mad bombers faster than you can root them out and mad dirty bomb bombers are in the batter's box. Strategic planning for a response to a dirty bomb is essential unless we want to die of 100 dirty bombs. I hate to admit it but I do think radical Islam is merely the military arm of the world Islamic movement which has always been "a convert by the sword" evangelic religion. The idea that "moderate Islam" actually opposes the work of their military is not born out yet by their actions and activities.
mayhap this was a heads up for the super-silent Muslim majority. Perhaps they need to know that their deafening lack of condemnation of the barbarism, coupled with not a whisper of refutation - could make one wonder if they are not simply playing cozy, waiting for what is the Muslim modus operandi - to do their dirty work until they've gained - or bloodied enough ground to allow them to step out into the open. If they aren't with us = then where are they? No room for mugwumping in this war - the wider war, the "kill the infidels war."
