Japan was in the wrong. It was a criminal aggressor. The idea that the Japanese people should be able to sit back in their admittedly lovely gardens and sip sencha tea while their armies were committing massive crimes against humanity is a grotesque notion. The best way to show the Japanese people the horrific nature of war and occupation was to bring it to their doorstep. If they want to portray themselves of victims, it should be of their own leadership, not the countries that needed to defeat them.
