Appointment of special envoys and hawkish Clinton as Secretary of State is a bad move by Obama. World had enough of American arm-twisting diplomacy.
Obama should think of engaging world leaders as equals. As he said in his inauguration speech, the world has changed. You will make enemies if you act like king of the world. You are definitely the most powerful man in the world, be humble. Your inauguration pomp showed the world that you are not what world expected.
