Jessica Gavora at The Atlantic:
The notion that America is an idea has always lifted up our country, and for good reason. The fact that America was founded on the principles of the Declaration of Independence and the governing limits of the Constitution makes us unique among nations. Most countries trace their origins to tribal identity. But America has its origins in the revolutionary idea that the government cannot deny men and women an equal opportunity to life, liberty, and the pursuit of happiness. Both our friends and foes have recognized this difference. No less than Joseph Stalin railed against American “exceptionalism” when our workers refused to join in solidarity with his murderous revolution of the proletariat.
