The city won for Allah from the Giaour,
The Giaour from Ottoman's race again may wrest;
And the Serai's impenetrable tower
Receive the fiery Frank, her former guest;
Or Wahab's rebel brood,who dared divest
The prophet's tomb of all its pious spoil,
May wind their path of blood along the West ...

-- Byron, Childe Harold's Pilgrimage , 1812,

as pointed out by Christopher Hitchens in the Atlantic.

Weirdly prophetic, or perhaps Byron was a simply a man of extraordinary insight.
