Final answer:
The term 'immortals' likely alludes to mythological narratives or metaphorically describes influential figures in history whose decisions affected war's continuation. In history, individuals' decisions have played a role in perpetuating conflicts due to political, economic, or ideological reasons.
Step-by-step explanation:
The involvement of immortals to perpetuate a war seems to be a reference to mythical or legendary narratives rather than a factual historical event. Such language might feature in discussions about classical epics or mythologies, such as the role of gods in the Iliad or similar stories. However, if the question pertains to a historical conflict, it would be necessary to interpret 'immortals' metaphorically, possibly referring to enduring political or military figures whose decisions influenced the continuation of warfare.
In historical conflicts, key figures and leaders have often played crucial roles in the decision to persist with or end a war. For example, during World War I, leaders were reluctant to capitulate or propose peace as they believed their nations could still prevail. Likewise, in the Genpei War in Japan, after the conflict had officially ended, Minamoto no Yoritomo had to ensure the fighting ceased, reward his followers, and establish a working relationship with the capital's bureaucracy, which significantly shaped the future governance of Japan.
In conclusion, while the phrase 'immortals' is not commonly used in serious historical discourse, influential figures have historically been involved in the decisions to continue or end wars, often driven by political, economic, or ideological motives.
