"Many classic war movies are among the most celebrated films in the history of cinema. But there are a few historical periods that seem to be wildly overrepresented in the pantheon of great war flicks: the two World Wars, the Cold War, the US wars in Vietnam and Iraq.
The twentieth century, though, was chock full of small wars that, for one reason or another, are less frequently made into movies.
Why are they neglected? Maybe it's because the history isn't widely known. Or maybe it's because in some cases the history is familar, but it's still too close for comfort."
