The fact that you experience such miserable feelings, really miserable feelings when you are young is miserable by itself. That is why I definitely don't want such devastations to happen again, and I don't want the generations of my children to experience that.
There has been the war going on in Vietnam. If it turns into a nuclear war by any mistake, the war itself will be beyond Hiroshima and Nagasaki. Imagining the power of nuclear weapons nowadays, I'm afraid that the situation would be even more miserable. It is not such a wishy-washy matter as prohibiting the nuclear power. We, humans, will bring ourselves to ruin if we use them one more time. It is the destruction of the earth.
