In yet another example of this administration's rejection of American exceptionalism, science adviser John Holdren says the U.S. can't be expected to always be on top. How uninspiring. How wrong. A little more than a year ago, the president himself said much the same thing at a NATO conference. "I believe in American exceptionalism," Barack Obama said, "just as I suspect that the Brits believe in British exceptionalism and the Greeks believe in Greek exceptionalism." In other words, America might think it's special, but so do other countries. And there's no reason to believe they're wrong. It's all relative. American exceptionalism is the idea that this country is set apart by our liberty and independence, our strength of character and our dedication to family, work, fairness and decency. America, more than any nation in history, is the "shining city" that Ronald Reagan described, and the best hope for the future of mankind.
