Russia-Ukraine war: what is happening now? ➜

The origins of the crisis lie not in Ukraine but in Moscow. This war is all about keeping Vladimir Putin in power. He fears an invasion of democracy – coming over the border from Ukraine – which could threaten his position.

No-one on the western side made any written or formal guarantees about NATO expansion in 1991. But the debate about whether the Soviet Union could reasonably have inferred from what was said a promise not to expand is a red herring. The Russian leadership of 2022 has built its own version of history, including a perceived threat from NATO, to justify its actions.
