Because saying Obama was in Colombia at this time is a cover story for what he was really doing. I would bet every dollar I own Obama was part of Operation Cyclone headed up by Zbigniew Brzezinski, and was sent to Afghanistan to train and arm the mujaheddin.
He was the perfect person to do this. Likely born to a family with CIA ties, brought up in the culture, knew the language, young and could blend in, and probably he is legitimately intelligent.
Why do you think the CIA is uninterested in vetting Obama and his past education? Because it’s a cover story THEY likely created.
Heap big leap there, chief.
