The New York Times reports Iran is inching closer to building a nuclear warhead, but there are obvious inherent risks for the government if it takes any obvious (or not so obvious) next steps.
A too-often used cliche in the political world is "game changer," and I'm often loathe to use it. But in this case, I think it applies. Iran's efforts are meeting with universal condemnation and warning -- don't build a bomb.
What the international community does with the information that Iran has moved forward and what Iran does with the knowledge that it can complete a bomb if it wants to are sure to be closed watched by the international community. Not to mention the mainstream media.
