“Vladimir Putin submitted to the State Duma a bill on the termination of international treaties of the Council of Europe with respect to the Russian Federation.”

My interpretation: this is the point where Russia is starting to formalize the parting of ways with the West, and ceasing to see the future of Russia as part of the wider European community. Also, it might be that a problem arose when DPR and LPR joined the Russian Federation, and some foreign mercenaries that were sentenced to death according to the local laws can now no longer be executed, because Russia doesn’t have the death penalty because it signed treaties with Europe. There was internal pressure to remove such restrictions for several years already.
