If they want to kill each other, so be it. A line has to be drawn at unimpeded shipping in the world's waterways. I find the whole story somewhat odd. Suddenly and swiftly out of the clear blue regional pirates successfully assault international shipping. The world's tough-guy (USA) simultaneously goes jello spine. One country not known for its nautical warfare skills takes action and sinks a ship full of said pirates. The world's tough guy (USA) says not a lot can be done; the same tough guy with gazillions of dollars worth of satellite surveillance (a lot of it devoted to following the world's shipping), and recon drones with nasty arms.
Is Bush flipping O the bird as he leaves? Or is the military taking early orders and standing down from using force in the region? I don't know what is going on but I'm certain that we ain't seein' it all.
The problem is that the people who are (thanks to Nov 4th) in charge in nearly every Western country really do not have a clue about how anything works, apart from their own narrow field of interest (politics) - which means that they hand down policies and decisions that lean from the misguided all the way to the imbecilic.
An example of the latter might be, say, the RN (under pressure from the Government) having to beg Kenya to take the pirates they captured last week to prevent them claiming asylum in the UK - apparently, they couldnt be returned to the country
they had just sailed from in case they were injured as a result ( link -
http://www.timesonline.co.uk/tol/news/world/africa/article5193601.ece ). The Indians have less of these problems, and so their navy shooting up a pirate ship is unlikely to result in the tide of hand-wringing apologia, lawsuits and general condemnation that would result over here in the UK.
The solutions? Either convoys (better than random patrols, even now), or giving everyone licence to shoot pirates again - something will have to be done, as they have realised that they can make a lot of money easily this way (and if they have realised it, you can be sure that every other failed or failing state near a shipping route will be realising it as well). Q-ships would also be an amusing addition to the mix, especially if you fitted them with cameras and showed the results on prime-time tv.
