li- factors which determine whether oration will seek to aixjuin? nuclear weapun* didcr widely from country lo country. National needs and interests vary from ease to case, as do systems of government and decisi. in-making.

In addition. levels ofin nuclear matter* and the liases of politicalh1 military doctrine vary considerably from state to stale and within states.

Ill RESTRAINTS ON THE ACQUISITION OF NUCLEAR WEAPONS

hile lhe objective is tu prevent diversion, safeguard* per se are concerned more with detection than prevention. Like other internationalafeguard agn-enwiits could Ix- abrogated or violated.

We believe lhat Ihe inspection and verification provisions ol broadsuch as those administered by the IAEA and EURATOM are generally effective in fulfilling their limitedhey arc likely to detect any significant diversion of materials or equipment from the uses intended by the supplier. In addition, lhe risk ot detection iseterrent of someagainst the unauthorized use of materials and equipment cos'crcd.

However, there ore certain gaps and limitations in the safeguard systems. For example, sume of tlie earlier transactions in nuclear materia) and equipment were under no safeguards of under agreemenls of limited scope.

lav is no formal agreement in existence among all potential Suppliers (hat safeguards will be applied tor inx lenr materials oi equipment; such safeguards as arc applied result from the unilateral dci istons of the suppliers. While il is incscnt practice for the UK and Canada In require safeguards like those imposed Iry lhe US. France has rejected tbe poliey of automaticallysafeguards in connection with sales. Soviet and.Chinese policy with regard to safeguards is unclear. The USSR asast European countries arc active members ol lhe IAEA anil apputve the principle of safeguards, but no reactors in existence or under construction in the Sino-Soviet area have been placed under IAEA safeguards. Neither the USSR nor China lias In dateany olher countryeactor able to produce plutonium in quantitics sufheiert for weapons, except that Ihe Soviets may have furnished the Chinese priorith equipment and technology tor hnililingeactor. Nevertheless, reactor* now under construction in Czechoslovakia and East Germany svilh Soviet assistance will be capable of producing enough plutonium foi weapons. We do not know svhet)>cr any safeguards are applicable lo tbe.se reactors hut almost certainly these countries will not undertake independent nuclear sveapons programs.

There are no comprehensive controls over world trade In natural uranium, although then* is an informal nirangcmcut bttsveen the principal Westernof uranium and some other materials lo keep each oilier informed as to sales. It has Ivccn possible for Wh Israel and India lo Imy unsafeguarded uranium. I'lirlhcnnorr, lliere is im standard policy regarding lhe provision of technical infoiuiation or specialised equipment.

Thereubstantial increase in the number of nuclear power reactors in operation in comingonsiderable number art' now under const nut ion in India, Sweden, Japan. West Germany. Italy, and otherl) will produce some plutonium or olher fusiuiinhlcany willtarge quantities. To tlie extent thai these reaclurt are under safeguards, the country or agemy administering (he safeguards williemu olwhit use is made of the plutonium. However, competition in the tale ol rcactois already exists and is likely to grow. Stich competituin may erode the effectivi-lies* of safeguards, particularly if the competitors include suppliers from countries which have oo policy of strict tab-guards. Such erosion would be most likely in tbe fields of equipment ami ancillary technology.
