My understanding of the amendment itself, and possibly the officials will have an opportunity to look at it, is that because the United States is specifically named, it would limit it to the United States. It would give no authority to allow it to share it with any other country, because it's only allowing it to share with the United States.
I'd be happy to provide that to you. I've got a copy of it in French as well, if it would please the Bloc to have that.
