The only evidence you have to support the claim that he was an Indonesian citizen also claims he was born in Honolulu. So if Soetoro was lying about where he was born why couldn't he be lying about his citizenship?
Is that you want to believe ... that he’s lying about where Obama was born because you don’t want to accept the possibility Obama was adopted and became and Indonesian citizen?? AFIK, Soetoro wasn’t present for Obama’s birth, so at best, he would simply be ignorantly repeating what he was told by his wife, whom we already know isn’t particularly honest.
