Another of my alternative history threads:
Let's imagine that the Soviet Union had not collapsed in 1990, and thus that Communism had remained a world power and, during the 1990s, the main ideological antagonist of the capitalist West. Assuming that the September 11th attacks took place in this alternative world, I can think of two possible scenarios:
1) Soviet involvement in 9/11 is immediately suspected, and the Cold War becomes even tenser, triggering a new arms race. Meanwhile, the Soviets seek to form alliances with Islamic powers such as Iran and support non-state movements such as al-Qaeda in an attempt to undermine the West. Thus the two anti-capitalist, anti-individualist movements, Islam and Communism, become uneasy allies against the capitalist West.
2) After 9/11, the capitalist West becomes worried by the presence of alienated Muslim minorities, especially in Europe. The Soviet Union, which still controls mainly Muslim Central Asia, is similarly worried by its Muslim minorities. The US and the USSR begin to cooperate in counter-terrorism strategies and seek jointly to undermine overtly Islamist regimes such as Iran. Thus, the two secular ideologies, capitalist liberal democracy and Communism, become uneasy allies in the face of a religious third force.
Which of these scenarios do posters think more plausible? Any alternative scenarios?
