Many of the comments and edits in the Whales Vs Other Animals have spiralled off from the original question into the differences in the treatment of certain countries.
While currently much of the news on this topic focuses on Japan, to my reading this appears to be because Japan's current position has changed from "Scientific" Whaling to openly commercial whaling, and that naturally focuses the discussion on Japan. Whaling in Iceland, Norway and various indigenous communities continues much as it has done for decades and without a visible change there is no basis for a fresh news story.
Politically is there any basis for the belief that Japan in particular is singled out for criticism more than other whaling nations or communities?
The last official EU statement that I could find didn't appear to mention any countries at all by name. Older statements that specifically criticise Japan appear to focus on the disguising of commercial whaling as scientific, rather than whaling itself.
