Clay welcomes Colorado historian Walter Borneman to the program. Borneman has written more than a dozen books, from the events at Lexington and Concord to a soon-to-be-published history of the American West following World War II. He's a public historian with a wide reach. The great question is: where are we as we approach the country's 250th birthday? How did we get here, and where might we be headed? Does a study of American history help us understand what feels like an unprecedented moment in our national destiny? Will we survive this current crisis of national confidence? Clay's conversation includes a discussion of the sweep of the Europeanization of the North American continent, with particular emphasis on the presidency of James Polk, an unapologetic expansionist, and, of course, Thomas Jefferson, who may have been our most intense national imperialist.
