If you take the time to listen to an upset child's story with empathy, and guide the child toward figuring out the root of the problem, then the result is often that the child not only calms down, but also in the future is less likely to get so upset.
It is my view that there is no sensible military use for nuclear weapons, whether "strategic" weapons, "tactical" weapons, "theatre" weapons, weapons at sea or weapons in space.
