"A bad workman quarrels with his tools" English proverb. Sir General Stanley McChrystal left his office to sir General David Petraeus. The specialist "to crush" and "to kill" has been replaced by the specialist "to get a deal" and "to make a price". McChrystal goes to Senate or even the Presidential election, leaving Petraeus with corruption and opium poppy and leaving American and other soldgiers with Taliban.
