As a child, no one would accuse Barack Jr of wrong-doing if Stanley Ann Dunham Soetoro had allowed him to become an [exclusively] Indonesian citizen in the 1960's.
However, by 1981, Stanley Ann Dunham had divorced Lolo Soetoro, and had moved to Pakistan [on some liberal do-gooder mission], and, at that point, Barack Jr, who was [or is believed to have been] born in August of 1961, would have been an adult, of the age of 19 or 20.
And if Barack Jr, in 1981, as an adult, travelled to Pakistan to visit his mother, and if he used an "exclusively" Indonesian passport to make that trip [remember, there is no dual-citizenship in Indonesia], then he would be proving that, AS AN ADULT, there was a time when he did NOT consider himself to be a citizen of the United States of America.
And if that's true, then there are huge legal and constitutional questions involved in his attempt to ascend to the presidency of the United States of America.
Actually, let me amend that - I seem to recall reading somewhere that the Dunham/Soetoro divorce might not have been finalized until about 1988, so it's possible that they were merely "separated" at that point.
It seems that your view that as an adult “there was a time when he did NOT consider himself to be a citizen of the United States of America.” is at best your opinion unless you have just neglected to spell out some law or point out where that would really revoke his US citizenship.
Again he could of been ignorant of Indonesian law and unaware of what it appears to be to outside viewers such as yourself.
You have this wrong. Obama visited his mom who was in INDONESIA, then he travelled to Karachi Pakistan, to stay with an unidentified family there for 3 weeks. He then travelled to the muslim city of Hyderabad, for another week.
