Why I This Our Job?

From Fox News: Navy SEALs have boarded and taken command of an oil tanker that was seized by three armed men at a Libyan port earlier this month, thwarting an attempt by a splinter militia group from selling nationalized Libyan oil on the black market.  
A Pentagon spokesman said that the operation was carried out Sunday night on orders from President Obama in international waters southeast of Cyprus, at the request of the Libyan and Cypriot governments. There were no casualties. The USS Roosevelt provided an embarkation point for the SEALs as well as helicopter support and served as a command and control and support platform.
A group of around 30 men from Navy SEAL team 2 approached the Morning Glory oil tanker using rigid hull inflatable boats and used ladders to get on board. Two AK-47’s were found on the ship, but no shots were fired.
The rebels are detained on board and will be handed over to Libyan authorities. The SEALS have since left the ship but 25 sailors from the USS Stout are now on board. http://www.foxnews.com/world/2014/03/17/navy-seals-board-take-control-rogue-libya-tanker/?intcmp=latestnews
So, why is the job of the U.S. military?  Why are we doing the bidding of the Libyan or Cypriot governments?
Just more Obama stupidity.
