When fantasy crashes into reality, fantasy invariably comes off second best. This is what happened when Mikhail Gorbachev became Chairman of the Soviet Communist Party. He might have been a Communist believer, but he was also a trained economist. He looked at the books, saw that the USSR was a superpower only in military terms, a pygmy in everything else, and realised that this simply couldn't go on. And so ended the USSR.
Fast-forward to today, and the situation is almost the same. Apart from raw materials and the occasional weapons, Russia makes absolutely nothing that anyone wants to buy. It is an economic pygmy with a shrinking population, and I can't help wondering whether this is a desperate attempt by Putin for relevance in a world where Russia is being supplanted by the big neighbour, which has been much cleverer (Deng Xaioping keeping political control but unleashing the traditional entrepreneurial abilities of the Chinese). The rising power of the big neighbour probably concerns him, and he wants to strut the world stage as a great power.
