i thought Saudis are Axis of evil for independent Turkey, you thought different. Respect it. But in reality Saudis is problem at the every corner in middle east for us. Sudan, Eygpt, Libya, Syria, İraq, Lebnan, Somalia... i can conitnue to count Algarie, Tunus...etc. They are source of instability for every democratic West Asia and North africa country.
Before the wahabis the shia safavids and their successors were a source of instability many times in the middle east and anatolia.
Thanks to them we had to import the kurds to make a wall against them.
Ottomans dealt with the wahabis many times. Due to the Ottomans collapsing and weakening over time allowed the wahabis to form their own state which would become Saudi Arabia.
