In Denis Johnson's novel, "Tree of Smoke," a poignant observation is made about the motivations behind American involvement in conflict. The quote suggests that Americans lack a deep connection to the land they are fighting for, implying their efforts are rooted more in a desire to uphold a moral stance rather than a fight for survival or defense of their homeland. This perspective highlights the notion that their engagement is temporary and lacks the urgency that comes from personal stakes.

The statement also implies that Americans seek to fulfill a sense of duty to be 'good' by participating in wars, but their commitment is ultimately transient. The remark indicates that after a period of fighting, they tend to withdraw, returning to a state of moral contentment without fully embracing the sacrifices and realities of prolonged conflict. Such reflections evoke a critical view of how motives can influence the outcomes of wars and the experiences of those involved.
