The idea that the Soviet Union was tricked in 1989-90 is at the heart of Russia’s confrontation with the west
The current confrontation between Russia and the west is fuelled by many grievances, but the greatest is the belief in Moscow that the west tricked the former Soviet Union by breaking promises made at the end of the cold war in 1989-1990 that Nato would not expand to the east. In his now famous 2007 speech to the Munich Security Conference, Vladimir Putin accused the west of forgetting and breaking assurances, leaving international law in ruins.
