As the premiere episode of the new PBS documentary miniseries shows, America’s involvement in Vietnam can be tracked back to World War II.

In a global conflict of exploding bombs and shells—tens of millions of them on land, sea, and in the air—setting one off in Hitler's headquarters might seem like the simplest thing in the world. 

The August 1942 landing on Guadalcanal was a colossal improvisation, concocted on the fly to take advantage of a recent dramatic turn in the Pacific war. 
 

While military maneuvers train and test a force’s capabilities, they can also seem like an “alternate history” at times. Consider these fascinating front pages from September 1941, reprinted here courtesy of The Shreveport Times, describing the US Army’s big Louisiana Maneuvers. 

In a Q&A interview with Bloomberg.com's James Gibney, Museum Senior Historian Robert M. Citino provides some of the military background that the Christopher Nolan blockbuster leaves out. 

Senior Historian Robert M. Citino, PhD, on Christopher Nolan’s WWII epic: “Nolan is particularly good at weaving together war’s three domains: on land, at sea, and in the air. The air battles, often a weak and confusing bore in war films, are as well-presented as any I’ve ever seen, and the German Stuka attacks, especially, are terrifying. No war film is truly realistic, but Dunkirk is as good as it gets.”  
 

BLITZED: Drugs in the Third Reich
By Norman Ohler

Americans like to think of World War II as a “great crusade,” but if it was, the country certainly didn’t seem all that fervent about rushing into it. Think of it: by the usual reckoning, World War II lasted six years, from the invasion of Poland on September 1, 1939, to Japan’s surrender on board the USS Missouri on September 2, 1945. US participation spanned less than four years of that total, a little over half the war. Of seven campaigning seasons, the United States missed the first three and was active only in the final four.
