Again, Nobel touches on the theme of deterrence. He envisioned a time when the catastrophic potential of warfare would be so immense that nations would abandon conflict altogether. This idea eerily anticipates the nuclear age and the doctrine of Mutually Assured Destruction that dominated the Cold War era. Nobel's hope was that the enormity of possible devastation would force humanity to choose peace over aggression. It's a profound contemplation on how technological advancements can both endanger and potentially save us. His foresight encourages ongoing dialogue about the ethical responsibilities that accompany scientific progress.
