Have the US government trace/track the beneficiaries of piracy - it goes way beyond Somalis. Then publicly declare their names and offer the following bounty:
Tax free status and US citizenship to anyone who confiscates their wealth by any means. Make profiting from pirating a misereable, unpeaceful business.
Unless the profiteers surrender to US justice and forfeit their gains.
time to reform executive outcomes, and have them buld a Q-ship. I would imagine Lloys of London would see this as a good business decision.
