Excerpt:
When the Soviet Union was still in existence, many senior policymakers were concerned about the implications of differential fertility rates in its constituent 'republics', for it was clear that at some point in the near future these would lead to a situation in which the USSR would become more than 50% Muslim. Such a pattern was already startlingly evident by 1970 when the census revealed that the RSFSR's birth rate was already at sub-replacement level with an average of only 1.97 children per family. In Ukraine, the situation was only slightly better with the equivalent figure being 2.04, but in the Muslim republics of Azerbaijan, Turkmenistan and Uzbekistan the corresponding figures were respectively 4.63, 5.95 and 5.64. These sorts of contrasts of course are witnessed today across Western Europe, where indigenous Europeans are outbred by an assortment of Muslim immigrant populations: Pakistanis and Bangladeshis in England; Algerians in France and Turks in Germany to give but a few examples. The English, the French and the Germans are breeding at sub-replacement levels, whereas the resident Muslim populations are exploding.
Being reliant upon a conscript army the Soviets were concerned about the potential impact of demographic Islamisation upon the reliability of its armed forces. This was also an issue in which the Americans were interested, but from their perspective, the resultant tensions that demographic Islamisation would generate within the Soviet Union should be welcomed as it would help to undermine its stability.
