Had a viewing party with friends at my parent's house for that episode. Water in the glass (not sure what I would have thought of an actual martini back then).

Vietnam and the war is quite an interesting story. Occupation goes back to the 1800s with the French occupation. Considering how the Korean war went and its outcome, the Vietnam war outcome was no surprise. It's interesting how administrations learn nothing from history. Russia was in Afghanistan for 20 years. Then the US goes in for another 20.
