Throughout May 2010, a review of the treaty on the non-proliferation of Nuclear Weapons (NPT) is taking place at the United Nations, where its nearly 200 parties are considering the treaty's “state of health” and ways to eliminate nuclear weapons. This follows intense activity last month, in which the United States took important steps toward this goal. So it's crucial that the next important step not be missed: fully implementing the Comprehensive Nuclear-Test-Ban Treaty (CTBT). This requires U.S. ratification.
