Glad we're past April 12 and 13

So, you may have heard that there was a pretty big event here in DC this past Monday and Tuesday.  "What was it?" you ask.  It was the Nuclear Security Summit which brought together representative (read: heads of state and other high-level officials) from 40 nations for a two day session.  Secretary Clinton posted a blog entry on Diplopedia, the State Department's official blog.  Navigating around DC was tricky - I went to a concert on Tuesday night and although the Verizon Center is just a few blocks from my apartment, it took us an hour to get there due to all the road blocks and street closures!  What did you think about the summit?  Was goals was it trying to accomplish?  Did it work?
