Dissecting the Iran Memo

President Obama has tried diplomacy, but yesterday Iran announced that it's starting work on a new plant to enrich uranium. The President's fallback strategy is getting the United Nations to step up sanctions designed to prevent Iran from "reaching the threshold." That means developing the capacity to build a nuclear bomb. But what if that doesn't work? Sunday's New York Times revealed a Top Secret three-page memo from Defense Secretary Robert Gates saying the US does not have an effective long-range policy.
