Indonesian law does not supercede U.S. law. And U.S. law states that citizenship can only be given up by the citizen themself, and only when he or she is an adult. It cannot be given up for them and it cannot be relinquished by accident. And if this violated Indonesian law then it would be the Indonesian citizenship that would be fraudulent, wouldn't it?
He had to give up US citizenship...if yhe even had it..which I doubt when he became an Indonesian citizen. His stepfather..Mr. Sotero was Indonesian Muslim. He was sent back to Hawaii to live with his Communist grandparents 4 years later. Where he went to school and was mentored by Frank Marshall Davis. A well known Communist agent.
