this seems like a really stupid thing to do, as they're basically inviting US stormtroopers to take care of this piracy problem once and for all.
sure kim jong il is not far from actually building a nuclear bomb, and he's dealing out counterfeit US money to beat the band, and trafficking drugs, and flouting every international agreement they've ever been a part of... but he doesn't mess around with oil, and whaddaya know: his ass is alive (probably)
as every person in the world learned when US invaded Iraq:
go ahead and be an @$$hole, but don't f__k around with oil.
To the Somali pirates: jeez, guys, think you might have bitten off more than you can chew this time.
I predict this overreach will be the beginning of the end of the Somali pirates' halycon days, as world governments decide to take them more seriously, and send in some serious countermeasures.
I could be wrong, though.
