Still even Iran has people calling for the overturning of the theocratic laws. There isn't any major movement of the sort to overturn Saudi Arabia's even worse laws.
There isn't a way to network. Saudi Arabia is a much worse dictatorship. But certainly there is popular support - not necessarily majority support, I don't know about that; probably noone in the world does - for allowing women to drive, for some form of alcohol legalization, if strictly controlled, probably for less barbaric execution practices as well.
No. Forget it. Maybe in 1995. (Now - if the only alternatives were the continuation of the status quo and direct US takeover... you might be right.)
