Upon hearing the news of the deaths of his compatriots - Somali pirate Hussein told Reuters;
"The French and the Americans will regret starting this killing. We do not kill, but take only ransom. We shall do something to anyone we see as French or American from now."
But what has changed?
There was a time when shipping companies paid ransoms to the middle-men in Dubai (Google "Dubai" for the connection between some American businesses and Dubai for some context) and Kenya .
When payments started going directly to the Somalis - that's when the taking over of fully crewed American ships started.
Without the insider information given from Dubai to the Somalis - the Somalis thought that any ship was as safe a target as any.
When the middle-men were cut from the equation, that's when the killing started.
Maybe there is more to the Dubai/America arrangement than meets the eye.
Ask the Somalis.
