It should be noted that Saudi Arabia has expelled and deported 100's of thousands of Saudi citizens because they were guilty of having Yemenite heritage.
Additionally, Saudi Arabia has spent millions of dollars to build a wall on it's border with Yemen.
Of course, these little known facts are rarely discussed in the MSM, even when the duplicitous Wahabi bastards have the unmitigated gall to denounce Israel for building a separation barrier or even contemplating the transfer of hostile Arabs.
When I read about Muslims killing each other, I can only think 'faster, more'.
For when Muslims are busy killing each other they have less time to murder civilized human beings.
Should the Saudi royal family fall and the stability of the surrounding 'friendly' oil rich emirates become endangered, we can expect an oil crisis and catastrophic financial repercussions.
However, in the long term, this might be the best thing that could happen to the West.
Any set of circumstances that encourages energy independance and the end of the flow of trillions of petro-dollars to the Islamic enemy should be welcomed, no matter how painful the ramifications in the short term.
