ISIS is headed by Iraqi former Ba'athists turned into opportunistic Jihadists. They are deciding everything. The few hundred, at most 2.000-4.000 foreigners, (of which the majority are Chechens) from across the world are mainly used as cannon fodder especially if they are young (18-25) and inexperienced in wars which most are.
KSA has not supported any groups other than FSA and the Syrian opposition groups that are recognized as the legitimate opposition across the entire world.
There might be a few hundred private donors at most but they act outside of the state.
Besides there will be no blowback and there have never been any blowback in KSA. It's simply too strong, there is close to no support for that FOREIGN entity and the KSA military will deal with them in no time.
1 ancient Arab clan in the Northern Borders Region could destroy them if armed properly.
Also English. Nobody understand what you are saying lastly who are not from South Asia.

The vast majority of KSA was never ruled by any foreigners. People from KSA ruled others and people from KSA also founded 4 of the largest empires in human history. More than any other people. The legacy is the entire Arab world. From Morocco in the West next to the Atlantic Ocean to Oman in the East near the Arabian Sea and from Syria to the Comoros in the Southern Hemisphere.
Local rulers ruled btw, that gave their alliance to the Ottoman Sultan's. Back then nationalism did not exist and Ottoman Turkish was for instance more Arabic than Turkish, they used the Arabic alphabet, ruled an Arab system (Caliphate) used Arab titles (Sultan and Caliph) and that is why most Arabs supported them. Even during the Arab Revolt many Arabs (despite the prospect of becoming independent) fought with the Ottomans.
I am not talking about all those Arab Sultanates, Kingdoms, Emirates, Sheikdoms etc. who never were part of the Ottoman Empire and who were regional powers of the time of their own such as the Kingdom of Morocco, Sultanate of Oman, Kingdom of Najd, The Kingdom in Egypt etc.
In any case Makkah and Madinah are protected by Allah (swt) and same with its people.
You can have your daydreaming. I predict that a few rag-tag Baluch rebels will invade all of Iran. That's more probable.
