Sorry, wrong post. My mistake.
The answer is no, I cannot. Indonesian law can no more supersede U.S. law than U.S. law can supersede Indonesian. If Obama did obtain Indonesian citizenship as a child that did not strip him of his U.S. citizenship. And if Indonesian law had forbidden dual citizenship then it would have been the Indonesian citizenship that was invalid. And nothing in their law could change that.
But I will point out that the Indonesian citizenship laws in effect at the time Obama lived there do not forbid dual citizenship and most likely would not have granted Obama citizenship even if he was formally adopted by Soetoro at the time. So your argument is flawed to begin with. Law on the Citizenship of the Republic of Indonesia
