Say, what would happen if non-gov't-affiliated American terrorist cells began infiltrating Mecca and Medina with the intent of doing massive damage to their most holy sites?
Things that make you go "Hmmmm........."
Can't happen. Unlike us they have enough common sense to keep all foreigners out.
You may not remember but 10 or 15 yrs ago a bunch of Iranian nutcases seized the Grand Mosque in Mecca. It took Saudi troops with machine guns to blast them out killing most. The Mosque took heavy damage.
As a result the pilgrims from Iran were not allowed to go to Mecca for a number of yrs. And now they are allowed to join the insect parade around their idol but the armed presence of troops is still there.
Until that lunatic asylum is destroyed there will probably be no peace (you can add the mosque on Temple Mount in Israel to the demolition list too.)
