Vietnam appears often in the Historian arena. This is a short article on the very early years with a focus on Saigon in 1945:http://japanfocus.org/-Geoffrey-Gunn/3137/article.html

The summary:
Nearly thirty years have passed since the end of the “Vietnam War” or rather the “American War,” as it is known in Vietnam. But the American war in Vietnam originated in the French war to restore colonialism in the power vacuum following the Japanese surrender in August-September 1945. As the following article documents, early U.S. post-war planners seemed to have grasped the iniquitous nature of old-style colonialism only to have forgotten their ideals when confronted with an independent revolutionary movement in the early days of US-Soviet conflict. History has revealed the disastrous consequences of American escalation in Vietnam on the wrong side of history, just as the lessons of history appear seldom to have been learned as, one generation on, America plunges into no less disastrous military adventures in other theaters in pursuit of militant Islam tied to terror.
