@Kanami-chan, looking from his perspective, it is true. They sacrifice so much in this war only to lose with humiliation like that, it's like pissing on the dead soldiers who paved their way toward victory.
I get your point, I see the same with the Western countries, especially the US, who loves to flex its muscles in foreign countries while acting as saviours for some reason while in reality, they just make it worse for the locals.
My country, Malaysia (Tanah Melayu during WW2, commonly known as Malaya in English) suffered Imperial Japan invasion too, freaking British just left us as evidence showed in Singapore.
WW2 Japan shouldn't have started a war with the US in the first place. They lack the resource required to fight them, let even maintain a long war on equal ground with them.
