Nuclear winter from what? one Bomb?
Nuclear winter is only probable from massive use of double digit megaton weapons, most modern arms are multiple-action kiloton range, at most the fear would be some radioactive fallout depending on the wind... which is why it wont happen as all the countries in the vicinity are allies.
