> The british were instrumental in supporting saudi and arab nationalism

The Saud family didn't overthrow the Ottomans with the British. That was done the Hashemites, under King Faisal, and of course T.E. Lawrence (whose story was told in his own memoir, and later in David Lean's epic film Lawrence of Arabia).

In the subsequent post-WWI, post-Ottoman chaos, the Sauds conquered Mecca from the Hashemites, and established modern "Saudi" Arabia.

The Hashemites fled and established what is now the modern country of Jordan, which they rule today.
