John F. Kennedy, in his quote, said that mankind must put an end to war before war puts an end to mankind, which signifies that humanity must stop wars because unchecked conflict can destroy us all. In today’s Iran–Israel conflict, military strikes and retaliatory attacks have escalated across the Middle East region. This growing violence shows why peace and diplomacy are crucial to prevent further destruction and broader instability. Kennedy's quote reminds us that choosing peace now is crucial to avoid catastrophic consequences.
