Misha Glenny in The Guardian:
Russia’s invasion of Ukraine has triggered a long-term shift in the tectonic plates of history that even three months ago appeared extremely unlikely. We are only six weeks in but even now, it is clear this one event will have multiple consequences around the world for many years to come.
Books on current affairs and recent history always run the risk of being overtaken by events. The revolutions in eastern Europe upended many papers and books on policy, which were still confidently assuming that the Soviet Union, the German Democratic Republic or Yugoslavia would still be functioning states well into the millennium. (Even the CIA, as late as spring 1988, was predicting that no great upheaval in eastern Europe was likely in the coming years.) Such developments have consigned many a tome to the charity bookshops prematurely.
