" Now, I believe that war is never inevitable until it starts, but there has been a great proclivity in human history, and including in recent history, for war. "
- William C. Kirby

In the given statement, William C. Kirby suggests that war does not have a predetermined destiny; it does not just happen by itself but requires human actions and decisions to start. However, he notes that throughout history, there has been a tendency towards conflict, indicating a recurring pattern in how societies often find themselves at odds with one another.

The deeper meaning of this quote lies in its reflection on the nature of war and its causes. Kirby emphasizes the role of human agency in initiating conflicts, highlighting that wars are not inevitable unless people choose to engage in them. This perspective challenges deterministic views that might attribute the outbreak of war solely to external factors beyond human control or influence. Additionally, by referring to "recent history," he underscores how contemporary societies still face the same challenges and potential for conflict as those from earlier times, suggesting a need for vigilance and proactive measures against escalation.
