The issue isn't so much the debris from the bomb impacts getting into the atmosphere so much as the ash and soot from every major city in the Western Hemisphere burning to the ground. That said, there is at least some debate on how bad a nuclear winter actually would be, and whether people like Sagan made overly catastrophic predictions. But it seems to me that if you're going to tell me, "it won't be so bad, maybe only hundreds of millions will die from the after effects instead of billions", that is still waaaaay beyond the pale.
