Here's a headline that hasn't been written in several centuries: an international flotilla of warships is converging to battle piracy.

U.S. warships watched a hijacked vessel laden with tanks while other gunboats patrolled the dangerous waters off Somalia, but pirates still seized another freighter this week — and now hold about a dozen despite the international effort to protect a major shipping lane.

Military vessels from 10 nations are now converging on the world's most dangerous waters, but analysts and a Somali government official say the campaign won't halt piracy unless it also confronts with the quagmire that is Somalia.
