Among those who reflect seriously on the requirements of security there is general recognition of the urgent need for security concepts conducive to a gradual reduction of distrust among the major Powers and to mutual confidence. This is a matter of concern to all Members of the United Nations. Therefore, two years ago sweden initiated a General Assembly resolution calling for a comprehensive study of concepts of security. The Group of Governmental Experts appointed by the Secretary-General to carry out this study has adopted its report (A/40/553) by consensus and the report is now before the General Assembly. we hope that it will be seen also as a contribution to the fortieth anniversary of the United Nations The legal and moral foundations of security assume particular prominence in the era of nuclear weapons. Public opinion, religious leaders, scientists and JVM/3 A/C.l/40/PV.4 5 (Mrs. Theorin, Sweden) popular movements of many kinds are deeply troubled by the moral implications of the possible use of nuclear weapons. Increasingly it is being maintained that strategic concepts which foresee indiscriminate killing and destruction on an unprecedented scale, also in nations not directly involved, are incompatible with ethical standards of civilized life. More knowledge is available on the effects of the use of nuclear weapons. New studies confirm the "nuclear winter" scenario. There is general acceptance of the fact that nuclear war and survival are incompatible. Therefore, nuclear strategies cannot be regarded as the exclusive concern of the nuclear Powers. As the nuclear threat looms over mankind, the world community may legitimately demand that the nuclear-weapon States give full information about their nuclear-weapon policies, that is, what is usually referred to as their nuclear-weapon doctrine. The Swedish delegation may revert to this question later on during this session. BG/4 A/C.l/40/PV.4 6 (Mrs. Theorin, Sweden) 
**Analysis**
The text appears to be discussing the concept of security, particularly in relation to nuclear weapons and the moral implications of their use. It also touches on the need for transparency and cooperation among nations to achieve a more secure world. Given the focus on international relations and the role of governments in achieving security, it seems likely that the text is related to the categories of International relations, Humanitarian aid and relief, or Culture.
