Basically, what I'm telling you is this -- the regime in Saudi Arabia is not just the King, but the entire Saud-Wahab edifice. They are emperors ruling over lands and tribes conquered in 1918. They are a theocratic government and have been. They ban any religion except Islam and they have destroyed Sufi, Shia and Ismaili monuments and tombs in the country.
Their only allegiance, only ally is Islam and specifially the Salafist Wahab strain. They use the USA only for this purpose and have used it and American money since the 60s to pay for the spread of Salafist teaching across hte world
