One year ago, President Barack Obama made a bold pledge to "secure all vulnerable nuclear materials around the world within four years." His immediate follow-through, however, has been wanting. For instance, his fiscal year 2010 budget request to meet this goal was actually $200 million less than what the Bush administration allocated a year earlier for securing nuclear material abroad. In fact, the administration still hasn't defined what it actually considers vulnerable nuclear material. So, in essence, Obama has lost a full calendar year in his four-year quest.
