They’re just Japanese war crime apologists. You get used to them.
They’re the same people who’ll say that only Jews suffered from the Holocaust and completely ignored the sacrifices of the Soviets and the Romani people (mostly because they were freed from those camps by the Red Army in the East and the West never saw it). They’re the same people who’ll say that US trade with Japan in support of Japan’s massacres in China was just business. They’re the same people who’ll claim that Japan did nothing wrong until Pearl Harbour.
They are delusional, and they’re not worth your time.
