Regarding Saudi Arabia Mr Spencer says that America is compromised in its support of Saudi Arabia due to their need for oil. All the while the Saudis are funding the vast majority (it seems 80-90%) of Mosques in the West and in other places. I fully agree with this, the Wahhabi Finsbury Park Mosque in London for instance, was built by Saudi Prince Fahd and Prince Charles. Look at its appalling history & its current crop of hate preachers.
There is though the additional complication that should the Saudi's attempt to Westernise their internal life - such as to say, stop beheading people - and bring in what we consider normal freedoms, they will face an immense backlash from the enormously strong Wahhabists in that country. Civil war could foreseeably result. Of course this menace also makes it very convenient for the regime to avoid taking any responsibility for reform.
It seems to me that even now America is still opting for the lesser of these two evils, but there has to be some way to navigate through this for the benefit of all. Saudi Arabia is it now stands is a direct threat to all countries - including Muslim majority countries - due to its spread of orthodox, historic Sharia, which is all Wahhabism is.
