Book excerpt: Michael Shafer argues that American policymakers have fundamentally misperceived the political context of revolutionary wars directed against American clients and that because American attempts at counterinsurgency were based on faulty premises, these efforts have failed in virtually every instance. Originally published in 1988. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
