Taking a second look at Vietnam.

While we don't normally do previews, we thought we'd note that we are going to do a few, albeit very few, about the Vietnam War, following the recent Novik and Burns documentary on the war. 

This is, of course, well outside of the time period we try to focus on here, although we stray from that a lot anyhow.  And we wouldn't normally note that we were set to stray, but as this will be a short series, and we've otherwise been focusing more recently on the era we claim to be about, that we thought we'd note it.  Not that we're going to stop posing on other stuff, topical or otherwise.
