That would be the opposite of what I said. Sinn Fein has never been a friend to the US, and visa versa. The IRA has never been a friend to the US, and visa versa. Can't be more clear than that.
The US has never supported NorAid, and in fact classifies some of it's sympathies as terrorist organizations, along with the UK. NorAid is not and never has been supported by the US government. It does not represent the United States, and is a private organization.
