They are probably easy to attack though,Submarines.
I expect most big players all have trained suicide bomber dolphins by now,after everyone found out about the USA having them ages ago...
Would not be that tricksy for a country wishing to blow a sub.
Same thing with oil rigs,off shore drilling platforms etc...
Maybe not dolphins,but trained frogmen with limpets would be more likely-they have been learning that craft since WW1.
More likely again,its just a series of mechanical/technical accidents,but its good to speculate.
