In Denis Johnson's "Tree of Smoke," the character reflects on the nature of war, suggesting that much of it is built on myths rather than reality. This perception indicates that societies often elevate the concept of war to extremes, framing it as a grand struggle that necessitates profound sacrifices from individuals. The invocation of a higher power, like God, serves to justify these sacrifices, creating a narrative that frames conflicts as part of a larger, meaningful cause.

This perspective on war underscores the psychological need for something greater than mere survival, as the harsh realities of combat can lead many to question their motivations. Without a sense of purpose beyond the act of fighting, the inclination to abandon such a daunting endeavor becomes stronger. Therefore, the mythologizing of war serves as a crucial mechanism for maintaining morale and commitment among soldiers, reinforcing why individuals choose to fight rather than flee.
