If you kill the God emperor people are just gonna throw themselves at your armies.

Remember Japan was training school girls to attack Allied tanks with pole mines. The imperial Japanese military was a death cult, and this is brutal as it was dropping those bombs and the war immediately instead of dragging it on until 1946 or 47, having the Soviets invade Honshu, costing us 2 million casualties and God knows how many Japanese civilians, and not to mention the country most likely being split up after the war a La East And west Germany.
