I agree with this.
But nothing could be completely ruled out at this point given the lack of hard facts.
FMD refers to the seduced 13-year old in his book. And he may have taken dirty pictures of SADO. And if there is an alternate he is a good #2, even if unlikely.
But it seems Obama senior leveraged his marriage and child when convenient and ignored them otherwise.
He does claim SADO as his wife in the INS forms in August of 1961. But fails to mention his supposed namesake child.
He does not claim them in his annual INS forms until 1964 - when he is about to be booted out of the US. THEN he claims both. And claims to be married after the formal divorce is final. My feeling on the divorce is that it was filed to give Obama II a name before Obama senior left or after SADO realized he was not coming back for her.
It also get interesting in 1971 when Obama Senior comes back. Likely in an action to leverage is parenthood to get Obama II out of Indonesia with all the i’s dotted and t’s crossed when it came to guardianship - AND citizenship. His role as the birth father allowed for termination of Lolo Soetoro and SADOs parentage rights and likely terminated Obama II’s Indonesian (only at the time) citizenship.
It would be doubtful that he would let Obama II be acknowledged as his child or do the 1971 trip if we was not connected.
Finally, I believe Kenya to be what is called in the IT security world a honeypot. Some that looks enticing but is worthless. It keeps prying eyes away from a damning issue - that Obama II was soley an Indonesian citizen from at least 1968 (when he was removed from SADOs passport) to 1971 (when he left Indonesia for good).
I see no fault in any of your reasoning.
