It’s not even a treaty, the IWC really started as a trade organization to make sure there was hunting stock. Then came the moratorium Japan never signed, then they started letting in a bunch of non-whaling nations.
I think they don’t go after Norway and Greenland because they’re not so brazen about it. Japan is all “yup, we’re hunting whales, wanna watch”. I think Japan is really making fun of the IWC but nobody seems to get the joke.
I would agree.
Japan does not like to be bossed around.
If the IWC would back off Japan probably would stop whaling.
On the other hand Iceland has recently taken it up again so there has to be some economic motive for it. Beyond a lubricant that worked even in the cold of space.
