"The USS Nicholas was just west of the Seychelles in international waters Thursday when crew began taking fire from a suspected pirate skiff, NBC News reported. The Nicholas returned fire and disabled the pirate boat, then pursued the skiff until it finally broke down."
How stupid would you have to be to take shots at a fully crewed, 4100 ton US Navy frigate from a "skiff"? It's one thing for the US not to get involved in piracy in foreign waters but you would have to be pretty out of touch to think they wouldn't react to a direct attack.
