I'm not dissing Mark79 or his graduate professor, but here are some facts that haven't been adequately answered:
1. The immediate rebuilding of Hiroshima and Nagasaki with no ill effects on the flora, fauna, or human population from lingering "radiation". The rebuilding was just like any other post-disaster rebuild.
2. Militaries all over the world spent billions (EACH, per year) developing new "conventional" (real?) weapons like Daisy Cutters, bunker busters, FAB-3000s, etc. and many of these weapons create a literal mushroom cloud. Why advance the technology of death, at such effort and expense, when you already have nukes in your arsenal? Why are nukes (alone) so magically "off limits"?
3. No country, no tin pot dictator, has used a single nuke since 1945. Getting out my calculator, that's EIGHTY YEARS that nukes have been around, but despite many armed conflicts all over the world during that time, somehow we've been "lucky" again and again. And again. Not even a single LOSING country has lobbed one out of desperation.
4. There is absolutely a bogeyman fear-factor associated with nukes. Duck-and-cover, and all that. If they DID want to create fear in the population, in order to get them to go along with various programs -- the fear of a world-ending nuclear war would certainly do the trick.
5. The legend of Nukes also involves the LIE that mankind "could totally destroy the world -- if I wanted to!". What hubris! What happened to God being in control? The world will be tried by (God's) fire, not man's atomic bombs or No0ks. If it was MAN'S bombs that caused the "fire" then the Liturgy and Tradition would say "Who will come to judge the living and the dead, and the world by man's power" or "the world by man's bombs". NO. THAT'S NOT WHAT IT SAYS. God will start the "fire" that will destroy/try the world -- not Trump, Xi Jinping, Zelensky, Putin, Macron, etc. Or else it would be "Trump will try the world by fire" rather than God.
6. Most of you have never felt the destruction, the helplessness, the rage, the despair, from having your city destroyed by an enemy. I haven't either, but I have a gifted imagination and a gifted ability to consider things impartially. But imagine after so many dead bodies are carried out of buildings, etc. you somehow decide NOT to use a nuke on the group, faction, or country that did this. That is INSANE. And it happens again. And again. And again. For almost eighty years! These aren't all Christians. And these same "restrained, cool heads" are OK with things like firebombing cities, conventional missile barrages that approach (or exceed) the destruction of Little Man and Fat Boy, and civilian casualties. But somehow EVERYONE always 100% of the time gets cold feet for even the smallest No0k?
