The accounts given belov should therefore be considered only as probable indieations of the magnitude of the effects of nuclear l/ar' 1\8. Tnese accounts start with a brief overvi ew of the physical effects of a nuc.lear explosion, vhich are nore fu1ly treated in annex I. To render the d.escription less abstract, some nuurerical values are given which relate to a weapon yiel-d similar to those of the bonxbs against Japan.

Tn sections B to D beIow, the destructive lorrer of nuclear weapons is applied to different war scenarios. section B" dealing with a linited nuclear attack, addresses some rather tbeoretica"l cases of nuclear riolence between nuclear- 'weapon States and then proceeds to explore the possible results of DucIeaJ aggiession against a non-nuclean-weapon State' Section C attenpts - in one simplified example - an analysis of the consequences if theatre nucfear lteapons vere to be extensively used in a super-Power conflict. Section D' which d'raws on the voluminous united states fiterature on the subject, is a condensed tleatment of the counterforce and countervalue types of strate8ic nuclear exchange betveen the super-porrers but also intiicates some of the global consequences' including the social and economic ones, that night fol-l-ow from a lalge-sca1e nuclear var.

**Analysis**
The text appears to be discussing the potential consequences of a nuclear war, including the physical, social, economic, and political effects of such an event. It does not seem to focus on any specific economic development, natural resources, or industry-related topics, but rather on the broader implications of a catastrophic event.
