Quite the opposite, bombing Mecca would be used as proof that we are the Great Satan, intent upon destroying Islam and warring upon Allah.
I've spent quite a bit of time in the Mid-East, both deployed in Iraq & Afghanistan and on business trips to the Gulf states. While justifying political violence is easier with Islam than other faiths, most Muslims are trying to just live their lives in craphole countries. Extremist groups are fragmented and often fight each other more than try to strike the West.
Bomb the Kabaa, and you prove to general Muslim population that ISIS and other extremists were correct all along. Muslims around the world would feel obligated to fight The extremists and they and current governments would unify against the external threat and launch a real Holy War against the infidels. It would be violence, death, and carnage on a scale we haven't seen since WWII.
Correct to read: "...Muslims around the world would feel obligated to fight. The extremists and current governments would unify..."
Agreed.
#37 The Saudi’s have already destroyed Mecca. They knocked down all the ancient buildings associated with Mohammad and anything Islam or Christian and put up hotels and highrises.
It is a Disneyland of stampeding muslims every year.
