Uh, I think you are confused as to what this "Graph 500" is measuring. The "Monty Pi-thon" contains 32 Raspberry Pis, which are less powerful (while using more electricity) than a single quad-code Intel desktop computer.
I think the issue is less dumb nationalism than the dumb belief that ARM will deliver better performance/watt for supercomputer applications.
