Somalia: Pirates' Mother Ship?

NPR does a nice job here with a discussion of the pirates of Somalia plying their trade in the Gulf of Aden:

The International Maritime Bureau, a Malaysia-based agency which tracks piracy world-wide, says the some pirates appear to be using "mother ships," to bring their speed-boat crews out into the sea lanes where they can attack.
The United Nations passed a resolution in June authorizing "all necessary means" to repress piracy in the region, allowing foreign warships to enter Somalia's territorial waters in pursuit of pirates. The resolution acknowledged that Somalia has no power to interdict pirates or patrol its own coast. In fact, the country has not had a central government with any significant power since warlords overthrew dictator Mohamed Siad Barre in 1991.
But shipping companies and piracy experts say that so far, the nations that have the military power to take action under the U.N. mandate, haven't done so. "The U.N. Resolution has done nothing to prevent these attacks," says Pottengal Mukundan, the director of Commercial Crime Services for the International Chamber of Commerce.
There is a coalition naval force in the region, composed of ships from the U.S., Canada, Britain, France, Germany and Pakistan, which is reportedly tracking the hijacked vessels. But Mukundan says that once a vessel has been taken, it's too late for military action that would further endanger the crew.
