Why would it be inappropriate for a foreign court to deny a request to return a child to the USA?

Why would it be inappropriate for a foreign court to deny a request to return a child to the USA, when a seven-year-old girl told the Swedish Supreme Court in 1995 that she wanted to live with her mother in Sweden? The child was retained in Sweden in violation of a US child custody order. The problem is that US courts only care about parental rights and do not care about children’s best interest and handle children as chattel. While in many other countries courts do not care about parental rights and only care about children’s rights. This causes a conflict of law (parental rights vs. children’s rights). This child was born in Switzerland in 1987 to a US Diplomat father and a Swedish Diplomat mother, but has lived in the USA for more than one year, and was taken to Sweden with the consent of the American father under the condition that she will be returned to Virginia after two year and the mother would not take legal action in the Swedish court system and Virginia court system would continue to have jurisdiction until she is 18. The father has not heard of anything of his daughter since and she hates her American father because he did not respect her decision based on the remarks he made to the American media about this case on American news websites.
