I do believe you are on to something with the Soetoro angle (amended or supplementary BC). I think the Indonesian connection is the Achilled heal, and would not be surprised to see that BHO continued to use his Indonesian citizenship for student aid, passport, etc., as a person of mature years. Y’ALL NEED TO TAKE THIS SERIOUSLY. (No comment on the “birth announcement.”)
“Achilled heal” = Achilles heel
The place of vulnerability!
