A somewhat realistic doomsday scenerio except for the president ordering the bombing of NYC. Even more realism might have been the US offering assistance to the USSR for the cleanup. I say this because in the film, our defences are obviously better then the military of the USSR so for them to attempt retailation would not make sense. The additional loss of innocent lifes could not possibly make up for the initial "mistake" and tragic loss of millions in Moscow. This film highlights the reason we need to be less dependent on technology. Unfortunately, that is not the current trend in our society.
