I read that as "We have visited their sites, not found anything, been told to be 110% sure that they don't have any weapons, is it possible to be that sure?, i wish we had access to all of their documents. Nothing is said about them not being given access to the Iranian sites just that they should be as transparent as possible, very different thing. First is doing something wrong second is them telling Iran "Well you haven't done anything wrong, but you had better make sure you don't". So basically the US but Islamic then. I think that it's a bit rich calling for one side to compromise without any from the other. I'm a bit sick of the US and to a lesser extent the UK telling everyone that they aren't allowed Nuclear weapons because they are bad and that they aren't grown up enough to handle them. All the while not really dismantling our own stocks.
