More than fifty years have passed since the twin crises of Lebanon and Taiwan dominated the news. These two events have faded into history and are often regarded as being, at best, footnotes in the histories of the Cold War. The world in which they took place seems to have passed away a long, long time ago. Yet, when reading these monographs, it become apparent that these two crises were profoundly important in terms of the effects they were to have on American strategy throughout the rest of the century. Those effects are still in play today and even now they are affecting how the United States perceives the world and reacts to developments within it. Air Operations in the Taiwan Crisis of 1958 and Air Operations in theLebanon Crisis of 1958 were prepared by the USAF Historical Division . This book is a compilation of those reports with substantial additional material that updates and complements the original material. However, the integrity of the original text has been scrupulously preserved.
