I’ve been thinking about it. The last part of the question is whether or not nukes should be used again.
After much consideration, I don’t think they should be used again. Keeping in mind that most of the nuclear bombs in the Russian and US arsenal currently are exponentially more powerful than those dropped on Japan. Even a few going off would have a negative effect on any surrounding areas for dozens of years. A small exchange between two countries would be cataclysmic. If either the US or Russia launched everything they had, the world would be pretty much over. Those who didn’t die in the initial srikes, would wish they had.
Given the destructive force and subsequent fallout, it’s hard to imagine that any country would be allowed by the world to have them. They are a tool whose power far out weighs the intelligence of those who might use it.
My understanding of the WW2 situation, is that Truman chewed on the decision for some time, and with great thoughtfulness. He reluctantly made the call,based on much deliberation with his advisers.
Such is the weight of decisions a president of the USA may have to make. I hope Trump supporters realize the potential for global destruction that comes with the job. The mere chance that Trump may have to make decisions like that scares me beyond articulation.
