The quote from Milan Kundera's book "Immortality" highlights the inherent challenges of military strategy, particularly in the context of retreat. It suggests that engaging in conflict often leads to a necessity for withdrawal, illustrating how attacking can force one into a defensive position. The implication is that retreat is not merely a choice but a complicated maneuver that requires careful consideration and execution.

This perspective sheds light on the broader implications of conflict, whether in warfare or personal relationships. The struggles associated with retreat reflect the difficulties people face when trying to disengage from confrontations or conflicts in their lives. Kundera's exploration reveals the complexities of human interactions and the weight of consequences that can arise from choices made in the heat of confrontation.
