U.S. Versus Them: How a Half-Century of Conservatism Has Undermined America's Security, by Peter Scoblic, is up for discussion in this week's edition of the TPMCafe Book Club.

Scoblic kicks things off arguing that neo-conservativsm isn't an aberration, but an extension of basic manichean conservative foreign policy.

Jacob Heilbrunn, author of They Knew They Were Right: The Rise of the Neocons, responds that Scoblic is too quick to exculpate the left for perpetuating American exceptionalism.
