Barack Obama and the importance of public diplomacy

(http://news.bbc.co.uk/1/hi/8082676.stm).This link is for the speech president Barack obama made to the Muslim world in Cairo Egypt 4 November 2009. In is speech president obama called for a new beginning in USA relation with the muslin world.The president also said Muslim perceptions of the US must change.
"Just as Muslims do not fit a crude stereotype, America is not the crude stereotype of a self-interested empire."
Mr Obama said America was not at war with Islam, but would confront violent extremists who threatened its security. i will see this as the recent event that most influenced the importance of public diplomacy in contemporary world politics. according to Joseph Nye"Soft powers works by convincing others to follow, or getting them to agree, norms and institution that produce the desire behaviour" (S.Riordan,2004, page120). I will agree that president Obama uses soft power to impose is policies. write now one of Obama's main aim is to fixed the America's bad reputation and the way the world sees it.the war and market exploitation, made many states to lose faith on the USA.Obama is trying to change that. but is it not as easy going to does leaders say sorry and peace. no because of globalisation the world is more united people in different states parts of the world share information and culture in seconds via media or internet. if a leader is hated abroad that may effect is popularity in is own state.for this reason Obama is using public diplomacy as is main weapon to clean America's reputation. the speech he made to muslin world is very powerful tact for public the diplomacy. this will help restore trust of the muslin people and even government. I think that international public relation is a very important virtue for a leader. and Obama is proving that using public deplomacy is a very important tact in today politics. he is now popular all over the world and he is also trusted by many nations.
