Mitt Romney said that he sometimes had wished he were in Vietnam instead of France

It's all about Bush, explains David Kirkpatrick in the New York Times.

The missionaries … spent twelve hours a day [in the 1960s] knocking on doors, often ending up defending the Vietnam War or American race relations against tirades by the French. Mr. Romney was so removed from the tumult at home that he was surprised to learn that his father, George Romney, had turned against the war while campaigning for the 1968 Republican presidential nomination.

…The missionaries had often met with hostility over the Vietnam War. “Are you an American?” was a common greeting, Mr. Romney recalled, followed by, “‘Get out of Vietnam! Bang!’ The door would slam.” But such opposition only hardened their hawkish views. “We felt the French were pretty weak-kneed,” Mr. Hansen said.
