This work investigates how the dual pressures of Ostpolitik and Westpolitik shaped the trajectory of European integration during the pivotal years of 1965 to 1973. N. Piers Ludlow, a recognized scholar in European integration history, utilizes archival research to analyze the complex interplay between West Germany's diplomatic outreach to the East and the broader efforts to consolidate the European Economic Community. The book argues that these two foreign policy strategies were not contradictory but rather mutually reinforcing elements that defined the geopolitical landscape of the era.

Historians and political scientists frequently cite this work as a foundational text for understanding the intersection of national foreign policy and supranational integration. Experts highlight the author's meticulous use of archival evidence to clarify the often-misunderstood relationship between German Ostpolitik and the broader European project.
