Of course it must be technical, we need get away from the shout nuclear bomb approach, to how to build technical safeguards into energy programs. Then rather than be restrictive, we can start to move to open. Open is where we will find the real transgressors, because open will become the nuclear norm. People hide now, because a non western enricher, is an immediate target: to avoid an attack they try to hide and then they try to reach a bomb, so that they can't be attacked. This is the counterproductive mess it all becomes with the current logic. Maybe the US is waking up to this, of course Iran is entitled to nuclear energy, it is a right it has. So the world shoud be securing that right, while at the same time denying them a weapon. We woud be better to put all our effort into a workable system to deliver on this, to safeguard everyones rights, rather than to deny rights, that exist in international law.
