No sane person wants a nuke, but don’t get hysterical. Nagasaki and Hiroshima look better now than Detroit and have for a long time.
Overestimating the damage from a tactical nuke is as bad as underestimating the damage.
Hiroshima and Nagasaki have had long-term effects - along with all 350+ above-ground nuclear tests which have included hundreds of thousands to potentially millions of cancers, birth defects and other health effects, around the world.
Our government and the rest of the nuclear powers will never openly mention this because they could never afford to pay for the liabilities these massive amounts of harmful materials those detonations spread around the world. There is no single square inch of the Earth's surface that has escaped that contamination.
I worked in underground nuclear testing, nuclear effects testing, helped implement and verify the Threshold Test Ban Treaty and I was a MOS 5715 Nuclear, Biological, and Chemical Weapons Employment Officer.
