Russia would win because it have less large cities than USA.
When Russia bomb US, half of country would die, and when US bomb Russia, only 'few' millions would perish, since nukes would aim for concentrated area, which are rare in Russia, and in abundance in USA. Which mean Russia would end up less chaotic and more chance to restart the society.
