Americans did know that any money given to the Pakis would be used against India. The same happened with the earthquake aid. Many countries including the Americans refused to give cash aid and unaccounted aid to the pakis. If the US wanted it, they could have given the terrorism money with a differently stuctured fashion with built-in accountability. The US deliberately gave cash- a total of $12B in the past five years, knowing fully well that the pakis would use that money to buy f-16s, swedish and Italian radars and other anti-India weapons. The Americans are now using the media to feign innocence on the matter of pakis using the aid to arm against Inida.
