Myself i can't understand it how nations permit it. They are there to do harm to you same as being kidnapped. You can see them coming. I now if i saw a kidnapper coming after me i would grab my 9mm and start firing..
Enough of the morality of it. Put security on all vessels, cost hell of a lot less then millions you pay in ransome to these thugs. Wait until they get right up along side of you and mow em down with machine guns. Better yet arms with short range rockets and blow them out of the water.
After 2 or 3 incidents like this they would go back to herding sheep like they use to do.
Have pity on them ? no not me. not in any shape. They want to resort to terror.... time to draw the line.
