For once I have too agree... This is becoming properly worrying.
We should take particular notice that Iraq and Iran are cooperating, witness the su25 movements.
It would be nice to think the Saudis might use their toy box, but highly unlikely!
Not sure what the solution is that will not cause further escalation! Boots on the ground turns this into a major Islam versus kafir battle. Doing nothing risks our south London friend exporting his homies to come to paradise. Short of the old Vietnam solution involving boats I am at a very real loss to suggest something that is not totally ridiculous ie. involving buckets of sunshine or walk away and let them piss off Iran, Israel and eventually the Saudis and see what happens. Probably leading to something equally serious.
