The vast majority of modern weapons are intended to detonate at moderate altitudes like those over Hiroshima and Nagasaki which in turn means the fallout is very low compared to a ground burst. Hiroshima and Nagasaki started rebuilding in weeks after the bombs, not years or decades, because their was very little residual radiation after 14 days.
The whole point of a "fall out shelter" is to allow people to avoid the fallout during that 14 day period when it is decaying away. To an extent the same thing happens with a nuclear power plant, the decay products are extremely intense at shutdown and the core needs strong cooling for the first week after shut down to deal with the energy released. What destroyed the cores at Three Mile Island and Fukushima was lack of adequate cooling during that first two weeks after shut down. It isn't magic, it is physics.
I find it hard to imagine that you can not see the difference between a radiation leak from a failed fission nuclear power station and the devastation from a 1.2 megaton hydrogen bomb that will vaporize everything within five miles of it's ground zero.
Do you really believe the crap you just posted?
Yes because once again you are ignoring the realities. The vast bulk of the existing arsenal are 500 Kt or less in yield so talking about 1.2 Mt yield weapons as if they were the standard to go by is no more sensible that talking about the 9 Mt yield of the old Titan II missiles or the 50-100 Mt yield of the Tsar Bomba. The reality is if you took every existing nuclear device and set them off so that the area of damage barely overlapped at the edges you would only destroy one very small country in terms of "turning the surface to glass and leaving only Cockroaches behind" which was the claim you made in your first post on this sub topic.
Even if there are say 20,000 weapons today and they all glass over 5 square miles each that only adds up to 100,000 square miles of total devastation. What does that mean in real world terms? Well you could aim every weapon in perfect deployment at Great Britain and sterilize the surface of the island. If you aimed instead at New Zealand you would have a few thousand square miles left over. If you aimed at Japan you would have about a third of the nation left pristine. Aim at France and half the nation is left untouched. Aim at Turkey and 2/3rds of the land is untouched. Aim at Bolivia and over 3/4ths of the area is untouched.
If that doesn't make my point clear enough nothing ever will. We simply lack the capability to actually destroy the planet with the combined world nuclear arsenal. We could easily crash our current civilization, but that is a vastly different thing than killing everything everywhere which is certainly not in the interest of any but a few nut jobs who we work very hard at keeping away from nuclear technology.
Propaganda movies like "On The Beach" convinced generations of concerned people that we could kill everything accidentally in the event of a nuclear war. It was never true, but that doesn't stop people from repeating the myth as you did above.
This is what you wrote that I was responding to.

Today's active weapons range form 100 KT to 1.2 Megatons (1200kt) and a single SLBM can have eight 475kt independently targeted warheads on a single missile. A single Trident submarine can have 24 SLBMs each with 8 MIRVed warheads. The football that follows the president has access to something on the order of 500 MT of throw weight at any time. The Russians and Chinese can match us warhead for warhead.
There is plenty of evidence that a full blown nuclear war would almost certainly wipe out all life forms on the planet higher then a cockroach.
Particularly that last sentence, which is patently false as any rational thinking person should be able to figure out if they just stop and consider the actual facts in the actual real world.
