if the child had been adopted by an Indonesian citizen,

. . . He would then be Indonesian, as his school records did indeed indicate.

and now he wanted to return to Hawaii on his own, with his own passport?

His Indonesian passport...

as has been alluded to

Alluded to, maybe; but never proven. A lot of bullshit has been "alluded to."

So what it boils down to is that nothing is proven or conclusive. You don’t know how his name became Soebarkah, all one can assume is that for that name to be removed in August 1968, it must have been on her passport that she obtained in July 1965.

So it would appear he was named BHO2 Soebarkah before he left Hawaii?

Or he left the country with someone else?
