If there is nuclear war without nuclear winter, there would be a dramatic loss of industrial capability which would cascade through the global system. However, being prepared to scale up alternatives such as wood gas powered vehicles producing electricity would significantly speed recovery time and reduce mortality. I think if there is less people killing each other over scarce resources, values would be better, so global totalitarianism would be less likely and bad values locked into AI would be less likely. Similarly, if there is nuclear winter, I think the default is countries banning trade and fighting over limited food. But if countries realized they could feed everyone if they cooperated, I think cooperation is more likely and that would result in better values for the future.
