And how many ordinary bombs and rockets? Even during WW1 there was enough weapons to destroy the whole world. Theoretically. By the way there are actually 10,144 nuclear weapons according to latest data.
I'm not sure where you got your data, even the most conservative counts(ones that include only known or solidly supported numbers) by groups like ican estimate over 15,000(
Source), with the 23,000 number I originally quoted being a less conservative count, which assumes that no military in possession of them is going to give real numbers and extrapolates actual numbers from building programs.
Just because he coined it, doesn't mean much about it's use. As for the Kuwait fires, those actually
did cause some fairly significant regional effects. However, the smoke cloud was unable to breach the high altitudes that would cause lasting or global scale issues. This was primarily because the burning of oil is not an overly energetic reaction, in the grand scale of things. I used the proven data on the effects of volcanic eruptions as the practical proof of concept precisely because it provides an more energetic reaction, the eruption
pushes the soot/ash cloud into the upper atmosphere, and nuclear detonations would do the same. Again, the cooling effects of volcanic eruptions is a
proven climactic effect, not an estimate or guesswork.
There were similar articles in 1920-th that described gas holocaust just the way we now know nuclear. And both never happened for similar reasons. First of all you need to detonate all those weapons at the same time, you need to be sure that all of them will detonate and none will be destroyed by counter-measures before detonation, malfunction and such. And you need a madman in each country to push the button. And even Hitler didn't use his gas arsenal in 1945.
So, a single point first. I don't personally believe a nuclear apocalypse is actually
possible any longer. Countermeasure systems have rendered the nuclear arsenals of pretty much everyone inane. Save only in the case of mass saturation, which could still work, total destruction by nuclear arsenal has mostly become a non-issue. My points were addressing the faulty idea that
if it did actually happen, it wouldn't be so bad. Not,
if it will happen at all.
Having said that, you've got some flawed logic in the above quoted section. You do not need to detonate them all at the same time to get these effects, and you only need a single madman. The later, only needing a single madman, is the result of the current policies by the major world powers. As it stands, and this has been true since the Cold War, once mass launch occurs by one side or the other retaliation is largely released into the hands of the standby launch crews and early warning systems. It's even worse if any strikes actually hit, as that triggers a near certain independant retaliation by sub commanders who are inherently disconnected from the chain of command.
Finally, it can be argued that Hitler didn't use his gas arsenal precisely because he
wasn't a madman. Racist? Absolutely. A fanatic? Obviously. A madman? No, not at all. He would never have gotten so far as he did, enjoyed such support, if he were a madman who desired destruction for the sake of destruction. The idea that he was a "madman" is a comforting lie people tell themselves, to assure themselves that monsters like Hitler aren't like them. To pretend, in the dark places of human thought, that such monsters are really monsters, rather than something any human can become under the right circumstances.
