Which goes back to the original problem: money - I'm not sure anybody is willing to put up the money to do all this, I'm pretty sure most governments consider it "acceptable losses" if 1 out of every 20 ships gets taken. (That was a random number, not based on reality btw).

Shooting down the opposition isn't always the answer. What if - And this is just wild conjecturing mind you -
You stop the pirates, yay, shipping lanes are free - The leftover pirates then get so desperate they form into even bigger militias, suddenly you have a border war going on - suddenly there are pirates there as well and it escalates into some of the African countries going to war with Asian countries bordering close to them...

I am of course blowing things wildly out of proportion here - but I think that unless you have a seat in a Captains chair on one of those boats - or live there, you can't really say what should or should not be done.
We lack the whole picture, whilst shooting anything that even resembles a pirate sounds good in theory, we do know that theory and practical applications vary very much from what was intended to the end result you get.

I can understand people getting angry over this and want to kill every pirate there is, but again we don't have the whole picture here, and more often then not, more violence to solve a violent problem is usually an answer you should consider to be the last resort.

We'll see what happens next in the newspapers, but I doubt that the problem will be fixed very soon by a few well placed tactical strikes.
