There's 3800 active warheads and 10'000 cities. Many of the cities would need multiple nukes to be wiped out. Many nukes would get disarmed by iron domes, anti-ballistic missiles, etc. Nucular fallout is thing that I'm not sure about. Technically more efficient bombs are cleaner, but I didn't go too deep into this and I'm not even sure there's conclusive data. Overall I don't think it's anywhere enough to completely wipe out humanity. Not even majority of people would be killed. But definitely it would effect everyone. Even current events already effecting everyone.
