It's interesting the importance given to Vietnam in the Romney camp accounts. Though it's true Vietnam loomed fairly large in student consciousness in 1968, it wasn't central to the revolt. And I'm having a job seeing all those French doors slamming in the missionaries' faces on the grounds they were American and should get out of Vietnam. I suggest a more authentically French reason for shutting the door was that people selling religion on the doorstep just don't go down well here...
