As a Saudi resident until relatively recently my heart goes out to everyone affected - particularly our friends on Al Hamra compound with two little girls that I have just heard are unharmed.
Captain Sand Dune - respectfully - what is your beef with Saudi? 'The beginning of the end ...' is a common refrain in your posts and as for 'too much Saudi hospitality can be bad for you ...' - I just feel sorry that you clearly have no experience of the genuine generous Saudi hospitality that can be extended to foreigners.
Terrorists may claim nationality of the country in whose name they murder but they, at least in this instance, do not act with their blessing. If you had met even one true Saudi you would know this.
