Its development, and above all the desperate efforts to achieve military parity with the United States, had been costly. The economic growth of the USSR was at this time slowing down. None the less, its defence expenditure continued to rise at rather more than 5 per cent per annum and was probably taking up more than the whole increase in gross national product. One-third of all mechanical products in their final form were for military stocks, which was a serious handicap in an economy gravely short of equipment and machines. Most of the available research and development effort went to defence, as well as one-fifth of all metal production, together with one-sixth of the chemical output and about the same proportion of all energy consumed. Though the figures were made to look smaller by the Soviet Union’s internal pricing system it seems likely that by 1983 defence expenditure was absorbing something between 15 and 20 per cent of total GNP.
The Soviet Union’s ageing leadership, the character and outlook of which had been formed in the great patriotic war, had always relied heavily upon, and been very close to, the military. On grounds of age alone changes at the top were inevitable before long. Brezhnev had never made the mistake (from which, when it was made by others, his own career had so signally benefited) of indicating an heir apparent in the leadership, but change in the mid-1980s there would certainly be and with the introduction of younger men into the Politburo and the military high command, men who had not been conditioned in the same way as their predecessors, a shift in outlook and priorities could be expected.
Newcomers would hardly be likely to adopt more liberal policies. They would be hard-line realists, to whom the absolute supremacy of the Communist Party of the Soviet Union (CPSU), and the safeguarding of their own positions in it, would override all other considerations whatsoever. Nevertheless, changes in structure, organization and style would certainly take place, if only to demonstrate that the leadership had changed. For the old guard, therefore, time was running out. They had until about the mid-eighties and probably no longer to extract full benefit in their own way from the Soviet Union’s military strength and its recently developed capability for projecting that strength at a distance, and to consolidate the world position this created. Beyond that time the distortion demanded of the economy for maintaining that position could not be indefinitely sustained, even with a populace long accustomed to its drearier consequences. Moreover, the growth in Soviet military strength had quickened defence expenditure in other countries and this in turn had reacted on the Soviet Union which, even if it had been inclined to recast priorities and spend less on defence, found itself, as the direct result of its own policies, constrained to spend more.
There also loomed the spectre of an extensive and costly military re-equipment programme to replace material, much of which had been developed more than twenty years before to embody a rather different war-fighting philosophy. This would not happen all at once but could not, without encouraging growing weaknesses in the whole defence structure, be long deferred.
There were other tendencies which also pointed to an approaching climacteric. The population of the Soviet Union increased in the years between 1974 and 1984 by some twenty-five million, but only about a quarter of this was Russian. Most of the rest was Asiatic, in which the increase was at about four times the rates found among Muscovites. The greatest increase was in Central Asia. By the early years of the 1980s the population of the USSR included some seventy million Moslems. Impermeability to external influences continued, as always, to be a prime factor in the maintenance of the supreme objective — the total dominance of the CSPU. The complete exclusion of such influences, however, could not be guaranteed, even in the Soviet Union itself.
Hunger for Western-style consumables was found everywhere. Listening to Western broadcasting was common. Probably as many as fifty million people in the Soviet Union in 1981, according to Vladimir Bukovsky, were already receiving the BBC, the Voice of America,
