If you're curious about why anyone might ever have thought that Russian would become a major source of new slang words in English, read a prescient 1994 article from Foreign Affairs by the economist and columnist Paul Krugman. The first three paragraphs of Krugman's article are quoted below:

ONCE UPON a time, Western opinion leaders found themselves both impressed and frightened by the extraordinary growth rates achieved by a set of Eastern economies. Although those economies were still substantially poorer and smaller than those of the West, the speed with which they had transformed themselves from peasant societies into industrial powerhouses, their continuing ability to achieve growth rates several times higher than the advanced nations, and their increasing ability to challenge or even surpass American and European technology in certain areas seemed to call into question the dominance not only of Western power but of Western ideology. The leaders of those nations did not share our faith in free markets or unlimited civil liberties. They asserted with increasing self confidence that their system was superior: societies that accepted strong, even authoritarian governments and were willing to limit individual liberties in the interest of the common good, take charge of their economics, and sacrifice short-run consumer interests for the sake of long-run growth would eventually outperform the increasingly chaotic societies of the West. And a growing minority of Western intellectuals agreed.

The gap between Western and Eastern economic performance eventually became a political issue. The Democrats recaptured the White House under the leadership of a young, energetic new president who pledged to "get the country moving again"--a pledge that, to him and his closest advisers, meant accelerating America's economic growth to meet the Eastern challenge.

The time, of course, was the early 1960s. The dynamic young president was John F. Kennedy. The technological feats that so alarmed the West were the launch of Sputnik and the early Soviet lead in space. And the rapidly growing Eastern economies were those of the Soviet Union and its satellite nations.

Burgess wrote A Clockwork Orange in 1962, when anxiety about Russian economic and technological prowess was at its height.

In 1994, when Krugman wrote his article, many Americans were very worried about competition from East Asian economies, which seemed to offer a different and more successful model of socio-economic organization. These fears have also largely dissipated since the Asian economic crises of the late 1990s.
