Question: What does the US believe caused the country of the birthplace of Pao Sarasin to help Japan?

Knowledge 1: Pao Sarasin
Pao Sarasin died at Siriraj Hospital in Bangkok after a month-long hospitalization for a blood infection on March 7, 2013, at the age of 83. A royal bathing rite ceremony for Sarasin was held at the Wat Benchamabophit with Princess Maha Chakri Sirindhorn in attendance representing the royal family. He was survived by his wife, Thapuying Tawika Sarasin, and three sons, including Thai television host, Kanit Sarasin. [SEP] Knowledge 2: Pacific War
The official policy of the U.S. Government is that Thailand was not an ally of the Axis, and that the United States was not at war with Thailand. The policy of the U.S. Government ever since 1945 has been to treat Thailand not as a former enemy, but rather as a country which had been forced into certain actions by Japanese blackmail, before being occupied by Japanese troops. Thailand has been treated by the United States in the same way as such other Axis-occupied countries as Belgium, Czechoslovakia, Denmark, Greece, Norway, Poland, and the Netherlands.
