When this cartoon starring Bugs Bunny was released the United States were in a war with Japan and that is something you must keep in mind while watching it. Every couple of seconds the cartoon makes fun of the Japanese and I must admit it is very funny, although very discriminating.
Bugs Bunny floats somewhere in the pacific when he sees land. He thinks it is a quiet island but it is filled with Japanese warriors. First a small soldier, who keeps talking 'Japanese' the entire time, wants to kill Bugs and after he fails a very big one tries to do the same. Of course Bugs will win. After this he faces an entire army but with a smart plan he wins that battle as well. Especially this part is not very nice to Japanese people, although it will make you laugh. Again, the United States were in a war with Japan and even now people make fun about others when they are in war with them.
