Ok, let me be more specific, the US military was placed in Japan in order to prevent renewed Japanese militarism.
Norwegians whale also, but they do it in their waters. Japan is obviously throwing it's weight around and will probably soon decide to no longer recognise Australia's claimed waters as belonging to Australia. That would be the next step to creating conflict just as we see in the middle east.
So if you can see Japan doing this to Australia and don't feel worried, then that's fine, however as an Australian it does not make me feel comfortable.
I feel that Australia should be able to conserve the wildlife within it's waters and have that be respected by other countries.
Japan can whale, but I want them to do it in their waters and respect Australia, and I would prefer their military remain small as a result of not respecting Australian waters.
