Word of advice to Somali pirates. Don't hijack a US-flagged ship with 21-American crewmen aboard. Don't hijack a ship that's operated under the Pentagon's Military Sealift Command to deliver supplies to US forces overseas. And whatever you do, don't put a newly elected president in such a terrible political spot. If you do, it probably won't turn out well.
So, barring some act of Sepuku by the Somali pirates, the ball is squarely in Obama's court. Now he really gets to find out what it's like to be Commander in Chief.
