Vladimir Putin’s ire at the west and at Nato’s eastward expansion ostensibly hinges on a decades-old treaty provision the Russian president maintains is under threat: “the indivisibility of security".
The concept broadly states that the security of any state is inseparable from others in its region. Putin’s stated belief that Nato strategy puts this principle in jeopardy is at the heart of Moscow’s justification for its military deployment on Ukraine’s borders, where it has stationed more than 100,000 troops.
Russian foreign minister Sergei Lavrov repeated the complaint last week when he cast western allies as aggressors following intelligence assessments that Russia was plotting to fabricate a pretext for a full-blown invasion of Ukraine.
