Shifting the focus will not work. Israel is not a signatory to the NPT. It is not bound by it's acceptance of that treaty. Nor was Israel found violating the treaty. Iran is in a mess it made and the ONLY way out is to not only comply with the NPT, and it's Additional Protocols, Iran must now convince the world it actually will continue to do so. Trying to change the focus to Israel is accomplishing nothing except to undermine Iran's position. Recent efforts to negotiate with China to purchase fuel for the Tehran Research Reactor without supplying the feed material also undermine Iran's position.
