the saudis cannot do anyhting unless they get some backbone and oust the western armies from their lands and sell oil on market price. any careful observer would note that the same problem is with pakistan. only the armies are replaced by blackwater and the moolah they earn is through NATO supplies, selling mujahideen, massive funding for participation in war on 'terror', massive military support. all a game of money. the honest among them can only look on helplessly or die. [ofcourse one may wish to also read what islamic fiqh says on attacks on 'civilians' and 'non-combatants' and whether there is a difference between the two.]
