The quote from Joseph Heller's "Catch-22" suggests that the true enemy is not defined by allegiance or side, but rather by the danger they pose. It emphasizes the idea that in conflict, individuals may face threats from various sources, making it essential to recognize that survival is paramount over loyalty. This perspective challenges traditional notions of allyship and enmity, highlighting the complexity of relationships during wartime.

By stating that the enemy is anyone who can lead to one's demise, Heller reveals the absurdities and moral ambiguities present in wartime situations. The focus shifts from ideological differences to the instinct of self-preservation, urging readers to reconsider how they view adversaries in a broader context. This theme is central to the narrative of "Catch-22," where the absurdities of war often blur the lines between friend and foe.
