On one occasion during my dad's administration, when I went to Taiwan on private business (I was in the yacht business in those days), the government went all-out to greet me even though I came as a private citizen. Before I could check out the yachts there, I had to perform the official duty of laying a wreath on the tomb of Chiang Kai-shek, not as a yacht broker but as an official visitor representing the president of the United States.
Does that experience qualify me as an expert on Far Eastern affairs?
On the same trip my family and I were greeted in the Philippines by Ferdinand and Imelda Marcos, and invited to visit them in the presidential palace for cocktails and conversation. That was another meeting with a world leader.
Hillary's widely-touted experience is not at all unique. Any member of any presidential family has had similar experiences but not one of them ever even suggested that their travel and meetings with foreign leaders qualified them to be president of the United States.
Nancy Reagan, for example, had far more experience than Hillary, but she was content to be the loving wife of a president instead of crowing about the famous world leaders she met in her eight years as first lady and claiming it qualified her to be president. Unlike Hillary, Nancy tells the truth.
