Here is a video clip from a speech delivered by outstanding Conservative Charles Krauthammer in which he blasts President Obama for making the choice to reject "American Exceptionalism" in speeches he has made around the world and at the United Nations.
Krauthammer said Obama actually said he believes in American Exceptionalism the same way he is sure the British believe in British Exceptionalism, and the Greeks believe in Greek Exceptionalism. In other words, he does not believe there is anything special or exceptional about the American way of life, our Constitution, or our history. Krauthammer essentially says Obama had chosen a kind a path of mediocrity for the United States that makes us just one of many nations rather than a nation set apart to lead the world.
NOTE: I think Obama's rejection of "American Exceptionalism" is exactly what makes him so appealing to people like the Nobel Prize Committee.
