This book investigates the complex and often overlooked relationship between Israel and Transjordan during the pivotal War of 1948. Uri Bar-Joseph, a scholar of international relations, draws upon declassified archival materials from both Israeli and Jordanian sources, as well as memoirs and secondary historical accounts, to reconstruct the clandestine interactions and strategic calculations that defined their wartime alliance. The central argument posits that despite public animosity, a pragmatic, albeit tense, cooperation existed between the two entities, significantly shaping the war's outcome and the subsequent regional landscape.

This work is recognized for its meticulous research into a sensitive and often obscured aspect of the 1948 Arab-Israeli War. Scholars have noted Bar-Joseph's ability to navigate complex political landscapes and present a nuanced view of the relationship between Israel and Transjordan. The book is considered a significant contribution to understanding the intricate diplomacy and strategic maneuvering that characterized the conflict's resolution.
