Some hostage "think tank experts" are saying that the pirates are "businessmen" and are smart enuf to realize that getting dead does nothing for them.
If operating on that theory is logical, then coralling all the ships involved, could give the navythe upper hand.
"You turn over the hostage ships, & we will set your sorry asses safely back on land. No harm, no foul, no ransom."
Do not agree to OUR demands, you are in for a bad day.
The bull$hit of the "tail wagging the dog", has gone on far too long.
As Grumpy has said.. scramble the communications, and remove thier ability to coordinate movements, etc. [Most likely already being tried??]
Just speculating here. I am not a commo expert but, perhaps they have some US military communication equipment. This equipment frequency hops and is very hard to scramble.
Not sure if this is what they are using though and it is purely speculation.
