I studied German at the Defense Language Institute in 1971, and served in Berlin 1972-73. We had our share of bombings during that time, but we felt relatively safe. We went to a Kristkindlmarkt, and loved it. It was hard to hear that a truck had crashed into a Berlin Kristkindlmarkt in 2016, killing 12 people.
A schoolmate took Vietnamese, and died in Vietnam. May he rest in peace.
