disparity of stocks and production facilities y and differences in industrial, financial and technological capacities, so as to enable each to best observe the relevant deadlines. Chemical warfare capability can be done away with only by proceeding to the co-ordinated elimination of chemical-weapon stocks and production facilities, for the two elements are closely interlinked: it would be absurd to proceed to the destruction of a particular chemical agent while its production continued. There must be no possibility whatever for the procedure of destruction of stocks and dismantling of production facilities to be tantamount to enhancement of stocks . CD/650 page 2 I. SECURITY BALANCE The concept of security balance must be perceived as a necessity both by "possessing" countries and by countries which do not have stocks. Countries of the latter category have the same interest as States which at present have these weapons in seeing the objective of the convention attained in accordance with the agreed time-table. Management of the destruction of stocks and dismantling of means of production, including solutions to difficulties encountered in the course of these operations, constitute an essential element of the overall balance. Nevertheless, the practical application of the concept of security balance poses numerous problems because the existing stocks quite clearly differ widely in volume and military "qualities", and the production facilities differ in their possible status (specialized military facilities, civilian plants working for defence, plants serving a double purpose) and in their capacity. It does not seem possible to neutralize as from the entry into force of the convention : 1. Existing stocks: even a declaration giving their locations, in combination with international inspection, would not constitute complete assurance since there can be no immediate guarantee that the declaration actually covers the totality of stocks existing at the time of entry 
**Analysis**
This text appears to be discussing the destruction of chemical weapons and the management of their destruction, which is a complex process that involves international cooperation, security, and diplomacy. The text highlights the challenges of destroying chemical weapons, including the need for a coordinated approach and the difficulties in verifying the destruction of stocks and facilities. The text also touches on the concept of security balance, which suggests that countries without chemical weapons also have an interest in the destruction of chemical weapons.
