You cannot have dual citizenship in Indonesia. At 18 he would have had to confirm he wanted to be an American citizen and if he didn’t then he would remain an Indonesian citizen. I have a cousin who settled in England after he retired from the military. At 18 they had to renounce either British or American citizenship.
He traveled in 1981 to Pakistan and at that time Americans were not allowed to travel to Pakistan except on Government business and you had to be Muslim. He sure didn’t use an American passport in 1981. He was over 18 when he traveled so the time to renounce his Indonesian citizenship had passed. That is why Berg wants the paperwork when he swore allegiance to the United States at 18 if he was born in Hawaii and his Kenyan grandmother made it up that she was at his birth in Kenya.
(The latest video from the Obamacrimes.com website clearly points out why 0bomber is NOT qualified to run for office):

"Since Sen. Obama has neither renounced his U.S. citizenship nor sworn an oath of allegiance to Kenya, his Kenyan citizenship automatically expired on Aug. 4,1982.
