Sources on the Vietnam War

Aug 2012
I'm looking for recomendations on resources on the Vietnam War.

I'm looking for two types of materials:

1. general overview

Something that gives a general history of the war (prelude, the war itself and maybe a bit on the aftermath). Doesn't need to go into a great degree of detail and focused more on politics and diplomacy than the military aspect.

2. different views on the justifiability of the war

Something that gives different points of view on whether the war was justified or not. If there's a good debate on this, that would be great.

I'm looking specifically for video and podcast material.
