Harsher in Hindsight: "Stink Bomb," after one delves into the story behind the Fukushima Dai-ichi power plant disaster. The problem in "Stink Bomb" escalates because the Japanesehigher-ups try to save face by obfuscating the truth, fudging data, and keeping secrets, which is exactly how the Fukushima situation was allowed to get to the point it reached.

A protest group in Cannon Fodder is arguing against the use of hazardous materials in the gunpowder used to fire the shells. The father who works at one of the enormous guns is later reprimanded (for something that wasn't even his fault) and forced to stand within the firing chamber that is normally evacuated but for one operator, without his mask on. Given how pallid and haggard the art style makes everyone look, it adds more horror with the Forever War slowly killing its population from within (for no reason at all).
