"The Teams Have Been Rebalanced"

Explanation: In WW2, the fascist/pseudofascist government of Imperial Japan pushed hard the idea that traditional Japanese ‘honor’ forbade surrender as the most humiliating of all fates, even worse than death!

… but historically, samurai had little compunction about surrendering or swapping sides, save that noble ransom was less refined than in Europe - meaning you probably would want to extract a promise of mercy before surrendering, rather than taking it for granted like a European knight on a losing battlefield might.

FUN FACT: one of the many offenses which caused the great 16th century Japanese warlord Oda Nobunaga’s betrayal and assassination was Nobunaga’s mistreatment of one of his vassals. He drunkenly played a tune on his vassal’s bald head with a fan, and then threw that same vassal’s good porcelain into a pond. Supposedly.
