Trump has appointed the worst people. No wonder his foreign policy is a mess.

Look at who was front and center at the Group of 20 meeting in Osaka, Japan, and then in South Korea. Here was first daughter Ivanka Trump giving a cringe-worthy readout of Trump’s meeting with the Indian prime minister. Here she was awkwardly trying to insert herself into a conversation among the British prime minister, Canadian prime minister and French president as the managing director of the International Monetary Fund looked on incredulously. And here she was walking onto a stage as if it were a catwalk in Milan so that Trump could introduce her to U.S. service members alongside Secretary of State Mike Pompeo — “Beauty and the Beast,” as the president put it. First son-in-law Jared Kushner was also present in Seoul and Osaka although less visible. Perhaps he was tired from his trip to Bahrain the previous week to unveil a D.O.A. economic development plan for the Palestinians.

What president in his right mind would appoint a fashion designer and a real estate developer — neither with any relevant knowledge or experience — to meddle in foreign policy? In any other administration, Kushner or Ivanka Trump would be lucky to be appointed ambassador to the Seychelles. In this one, the crown prince and princess can do whatever they want.
