Karen Hughes: Public Diplomat

Karen Hughes has been employed by the White House since 2005, being a former adviser of President Bush when he was still the Governor of the state of Texas. Hughes' goal in working as undersecretary of Public Diplomacy and Public Affairs was mainly to work on the image of the USA in the Muslim world. That had to be done by operating on the country's responses to the anti-American speeches of the Muslim community toward the US public diplomacy. I personally beleive that Hughes did not manage to acheive that goal, and did not even get close to completing her task. I am convinced that she would have needed to participate in the decision making process of the country's Policy.
My point is that if the image of the United States is tarnished by an event (War on Iraq for example), no matter what Karen Hughes does, the problem will persist. If the Muslim world criticizes what the US are doing, then however you change the image of the country, the facts still show the real image of the world's most criticized nation.
PS

U.S. Public Diplomacy:

-->America will continue to be the symbol of hope and opportunity to the eyes of the world (shaping the American Dream)

-->It will also try to "marginalize and isolate" the terrorist extremists; by having other Muslims speak up against and condemn terrorism

-->Spread American values, considered as Universal values, and share the Story of America.
