Oh how I wish the basis for this story didn't exist.
Dolphins, all Cetaceans, are so much more intelligent than we give them credit for. I'm convinced that they are more evolved than humans as a genus. They are not alone...sea lions and orcas are also used by the US Navy.
The suffering of these creatures at the hands of humanity is disgraceful. Even this article is slightly light hearted about the trained dolphins but I'll be attempting to add to this post soon with more background info when time allows me to.
The US military has gone to great lengths to further their dolphin programme and to keep it from becoming public knowledge. They know how disgraceful it is. They just find their own ends will justify any means, as always.
