According to internal assessments within the UK government, the UK should prepare for the scenario of an unexpected collapse of the Russian Federation so that such events do not take London by surprise.
As they mention in the article they anticipated a much slower collapse and likely prepared for that. But at the rate it’s currently going, it’s quite astounding. The fragmentation and internal strife in Russia are certainly not over.
I did read one article that made a reference to this more being an “end of the beginning” rather than the “beginning of the end”. Which I agree with.
It hasn’t collapsed the federation overnight, but it’s certainly weakened it a hell of a lot.
