I don't know, but it just doesn't seem like a good idea to keep pissing off other nations. At some point, they're going to say enough's enough and start painting the pirate boats with smart rockets before they get close enough to fire back and that live-die thingie going to be granted. It's just a matter of time...
I cannot fathom how 4-6 pirates in a 30’ boat can overtake a tanker or freighter.
Put 2 guys with .50 cal chain guns and sink any boat that tries anything...
It is beyond stupidity that the shippers wont defend themselves
