Offering an impressive analysis of long-term historical patterns, population, and social changes, Graber presents a fresh look at current trends in world politics. "Making it fun (and even exciting), Robert Graber pursues here a very serious issue--the coming of a world state--and gives opposing sides of this debate fair and frequent airings. With his accustomed mathematical skill and ingenuity, he makes a case for the future unification of the world without the necessity of global war. Even the skeptics--and I'm one--hope he's right."
