Its like that retarded American rule about the right to bare arms, that really works doesn't it, and lets be honest, the world is not a harmony of people getting along, I wouldn't want my neighbour owning a shotgun if I knew he was annoyed at me.
They wish to enrich uranium under their own steam. Do I trust them to use it totally responsibly and not make nuclear weapons. Not really. But you either work with people or against them and in this case we can not work against them. It's their country at the end of the day. Yes it will unsettle the region but lets face it Britain and the USA are the masters at that and this particular region has never needed any help in being unsettled.
