There are more factors in a realistic nuclear war: - Quite a few nuclear weapons will be spent on military sites, which are often in low-population density areas. - Quite a few nuclear weapons will be used to destroy other nuclear weapons. - Nuclear fratricide, or nukes from the same side damaging each other in ill-coordinated explosions - Air defence destroying at least some missiles and especially planes. - Some bombs will be duds and fail to detonate due to bad maintenance.
