Today Japanese whale catcher boat was attacked by pirates named Sea shepherd and the boat’s crews were wounded. Now I don’t want to discuss about whaling issues, but how Japan will react against the pirates. Japanese whaling does not exceed the limitation of international law, but their performance clearly broke it. However, Japan’s boat did not counter emotionally. I evaluate this patience. It is because their attack was completely provocation, so the boat should not overreact. I think Japanese ministry have to do forceful action. Appeal only with words has no power to them, we studied it form their past action. However, regrettably Japan is in the situation that the forces can’t preempt attack. Therefore, Japanese ministry have to think means to oppose them.
