Saudi rulers castigating other Islamic religious nationalists?

Madawi Al-Rashid yesterday wrote an article on Saudi-Wahhabi criticism of Turkish PM Erdogan (See Saudi Wahhabi Leaders See Turkish Caliphate Threat). In this article, she explains the criticism of Suleiman Aba al-Khayil, the director of Imam Muhammad Ibn Saud University of Erdogan and Turkey. 

The criticism is based on a theory that Erdogan wants to establish Islamic caliphate or revive Ottoman caliphate and become the new caliph or Sultan. And as Imam Muhammad Ibn Saud University is considered the center of Wahhabi theology and jurisprudence and a defender of pure Islamic (read Wahhabi) creed against innovations, Suleiman found it necessary to refute this theory. Madawi reports that Erdogan and Turkey's (perceived) claims to caliphate were rejected by pointing toward Turkish 'blasphemy, debauchery and, amusingly, Turkish nudist clubs'. Suleiman questioned how a good Wahhabi Saudi can think of Erdogan restoring the caliphate as Turkish society is immersed in sin and is far away from 'true Islam'. Obviously, the real message for Saudis is that if 'true' caliphate is revived, it would only be on the basis of 'true' creed and under those who believe, uphold and defend the 'true' creed i.e. There is no real, authentic revival of caliphate, without Wahhabi ideology and Saudi state leading it.   

Without going into the merits of director's message, its interesting to see how Saudis, despite believing in Islamic religious nationalism, are trying to counter, discredit and de-legitimize other countries and movements that also believe in Islamic religious nationalism. 

The tussle between Iran and Saudi Arabia is old story. Since Iranian Revolution, Saudi royals have led the fight against the Shiite rafida. Iran and Saudi Arabia are continuing their decades-old verbal jihad. It appears that Saudi royals are more afraid of still to be manufactured Iranian nuclear bomb than already existing Israel's large nuclear arsenal. 

Saudi royals have also come out clearly against Muslim Brotherhood, another movement that believes in Islamic religious nationalism. They are funding and abetting Egyptian military's cruel attempts to destroy Brotherhood, cheering mass killings and mass sentences. The hatred against Brotherhood is astonishing as Saudi were the ones that saved Brotherhood from the previous onslaught of Egyptian military in 1950s and 1960s. Brotherhood, in return, provided the counter narrative to Nasser's Arab nationalism that was becoming popular in Saudi Arabia as it was in other Arab countries. 

Now, attack on Erdogan, again someone that has roots in an Islamic religious nationalist movement, shows a pattern. Are Saudi royals worried that their legitimacy based on Islamic religious nationalism is under threat and that's why they are attacking anyone who can be considered more legitimate? Does this feeling heightened because of Arab Spring or because of recent cooling off relations with the US?  

Saudi rulers find themselves in difficult position. They want their people to reject the West, but they have very close relations with the West and that is not hidden (anymore) from ordinary Saudis. Similarly, they proclaim their allegiance to Islam but their own lives are far from Islamic. Another fact that is now open to all Saudis. Finally, they profess to be Islamic religious nationalists, but also trying to promote Saudi nationality to counter the threat of extremists groups, like Al-Qaida.
