While there is a tiny bit of truth in your statement, Saudi Arabia changed a lot in 1979

Saudi King Khaled however, did not react to the upheaval by cracking down on religious puritans in general, but by giving the ulama and religious conservatives more power over the next decade. He is thought to have believed that "the solution to the religious upheaval was simple -- more religion." First, photographs of women in newspapers were banned, then women on television. Cinemas and music shops were shut down. School curriculum was changed to provide many more hours of religious studies, eliminating classes on subjects like non-Islamic history. Gender segregation was extended "to the humblest coffee shop". The religious police became more assertive.[
So it is up to debate, if Wahhabism really predates Islam extremism so far or at all. But regarding for Saudi Arabia I have little to no hope at all.
