The question is not who, if any, is stunned. The question is who, if any, can use it and profit. Obviously, the Greek government thinks it can use it and profit. It will be interesting to see if the the Germany will react and if so, how.
My overall impression is that the Greek government tried to use it clumsily. Unless its purpose is to blame the IMF for its own failures. Apparently, if elections were were held today, ND would receive more votes than SYRIZA.
