Again, your proposal it would do nothing is based on - what exactly ?
Not what I said, at all.
You were talking about thousands of nukes being used... Russia doesn't have that many targets. During the Cold War we planned on attacking empty military lots, on the off chance something might go there.
When the Pentagon suggested using nukes, Truman said, "Never ask me to use those horrible things again." In close calls and simulations, people invariably try to stop. If you're not a psychopath, you've got a threshhold. A nuclear war would reach that threshold in a matter of hours.
Anyway, we don't actually know how bad a nuclear winter would be. Partly because we don't know how many of the weapons would be used. In a way, I'm agreeing with you, I expect there would be a nuclear winter.
But we don't have everything we need to predict with reliability.
