Japan has defeated Sea Shepherd by means of a law that classifies Sea Shepherd's obstruction activity as "terrorism", combined with actions by Australia, New Zealand and the US to stop Sea Shepherd from operating.

Sea Shepherd does not engage in violence; it gets in the way of whaling ships. The idea that an inconvenient nonviolent protest is "terrorism" is twisted, but then, so is everything about Japanese hunts for whale meat that people mostly won't even buy.
