Bin Salman’s visit to London once again showed the real face of British politics. When it comes to money, guns, and power, London will cuddle up to any Arab autocrat. But that won't be all. The history shows that London washes its hands with dictators if or when they have ceased to be of use, or no longer buy their weapons or run out of cash or simply get overthrown. The Saudi impulsive prince should not be so proud of what is happening in London. He should definitely watch his back.
