Japanese victory announcements and a retreating front

Is this like Japan continuing to announce victories while the fighting moved closer to the home islands?

The joke exposes the contradiction between claims of repeated victory and fighting that has moved closer to Japan.

A question jokes about Japanese victory announcements continuing while the fighting moves closer to the home islands. The replies develop the contradiction through the language of tactical withdrawal and advancing in another direction. The geography of the retreat makes the claim of repeated success increasingly difficult to sustain. These are ironic descriptions of a propaganda problem, rather than quotations of a particular announcement.
