WASHINGTON: Soon after assuming office in 2009, President Barack Obama experienced a security nightmare about the possibility of Taliban in Pakistan acquiring a nuclear bomb, with the fear lurking in the back of his mind that the loose weapon could be headed for a major US city.
US intelligence told the President during a key Oval office meeting that they had received information about Taliban acquiring a nuclear bomb, says the latest book by New York Times journalist David Sanger, adding Obama's aides also worried about the leak of the news to both India and Pakistan.
