I know that movie well, @kyte! I found a copy just a few years ago, having originally seen it as a kid in the 80's... It was made specifically to try "wake up" Cold-war leaders to the fact that no one wins in these events - with some text at the end saying as such... (And I think I only watched it originally because it starred the guy from the Police Academy movies!)
Of course, even "better" was the BBC's 1965 doco-style production, "The War Game", that was banned before it was aired, because "the effect of the film has been judged by the BBC to be too horrifying for the medium of broadcasting". This however didn't stop my Social Science teacher showing it to us in grade 10... (It was released on vidoe in '85.)
The 1959 Hollywood movie "On The Beach" proposed that a global nuclear war left everywhere uninhabitable except for Australia... however eventually even Aussie land was exposed, and - everyone on the planet died.
The movie was re-made about 17 years ago here in Australia, with the same premise, for cable tv.
The thing is, no one really knows what the outcome will be from a global nuclear war. Certainly, if you're in a blast zone, it's goodnight, and if you're not in the blast zone, but within X km's, then it's either a really agonising but quick goodnight, OR a long long horrible goodnight, depending on X's value. And, if you're outside that area, depending which way the wind is blowing - you may also be affected. But... outside of those areas, there's nothing to say that "On The Beach" will come true. The areas around Hiroshima and Nagasaki to my knowledge did not directly suffer any radiation issues.
(Chernobyl, Fukushima, 3 Mile Island etc - were nuclear power stations that experienced meltdowns, and and will be uninhabitable for thousands of years. However, a nuclear bomb uses much less nuclear material, and ultimately - as seen in Japan's 2 bombed cities - life in fact went back "to normal" within a few decades, with no lasting increases in radiation/illnesses.)
Nuclear Winter however may affect some parts, or perhaps even the entire globe. This phenomenon is only a hypothesis at this point, but predicts drops of temperature as the sun is blocked by fallout etc, and will cause the ruination of crops etc. The duration of a Nuclear Winter again is an unknown, especially without having actual data on how many nukes may be involved or their power etc. But even a 6 month period would see millions die from starvation. My pantry would only see my family survive maybe a month at best!
I'm not, fyi, PRO nukes! I'd rather no one had them. I don't buy into the "well X has them so we have to have them to keep X in check!" mentality. But once you have them, I can see it being hard to give them up...
There are plenty of horrific images of nuclear destruction... but the shadows of Hiroshima should be enough.
All that was left of this person, was their shadow, burned onto these stairs when the bomb hit. There were several such examples documented by the US Army when they went in after the bombs were dropped. (Should I say... probably also Aussie troops, as the US sent a lot of our guys in first... I wonder why... No protection used whatsoever...)
** Please DO NOT google this topic. A shadow of a former human being is one thing to be etched into your mind. The other images that Google will show you from a search on this subject are MUCH WORSE. Images you cannot unsee. **
The ABC ran a few stories from Hiroshima's survivors during the 70th anniversary year on their website. One particular story of a girl who survived was just...
