America is turning 250, but the celebration is already running into controversy. In this episode of Apocalypse...Now?, I explore the political tensions, sponsorship disputes, and cultural conflicts surrounding America's semiquincentennial, from Washington, D.C. to Philadelphia. Then I kick off the latest installment of 250 Reasons to Love the USA with a look at 20 American inventions that changed the world, including the internet, the airplane, air conditioning, and the telephone. Is America too divided to celebrate its own birthday, or is arguing about America the most American tradition of all?
