The WP page about nuclear winter seems to indicate that while the concept is 
debated it's still supported by contemporary research (what is under debate 
is how dramatic it would be, which is what one would expect from a 
mathematical model) and that the main critic was a guy writing survival 
books. Also, there's a paper here 
http://www.uow.edu.au/arts/sts/bmartin/pubs/88spp.html about the comments by 
Dyson, Feynman and others where the author re-interviewed them a few years 
later with interesting results. In a nutshell, just like creationism and 
global warming today, it seems that this was instrumentalised in the US for 
local political gain by the usual suspects, which is probably why these 
"controversies" don't seem to cross the Atlantic and Pacific (or lose 
considerable strength when they arrive on the other side).
