Amusing to observe Obama responding to Putin. Too bad grandiose rhetoric is not a good substitute for effective leadership or sound policies.
Its not grandiose rhetoric, and it is effective
It is a dismissive sneer, designed to give the Palace Guard Media an opportunity to present BO as a cool customer with a cutting wit, during the next 1-3 twenty-four hour news cycles. And it is very effective at deluding those who get their news from the Palace Guard Media.
Unfortunately for the United States, BO's accomplishments on the world stage, as portrayed by the Palace Guard Media, bear the same relationship to real life international affairs as the accomplishments at the plate of a T-Ball player bears to Major League Baseball.
