What did Moscow's NATO move signal by 24 October 2021?

What was the picture for Russia and the West as of 24 October 2021? Two reports from the preceding days set the tone.

On 18 October 2021, Russia announced that it would suspend its mission to NATO in Brussels as early as 1 November. The decision was presented as a response to the expulsion of eight diplomats, accused of espionage, from the mission earlier that month. Moscow said the NATO information bureau and the military liaison in Moscow would also be terminated.

A day later, on 19 October 2021, the Federal Bureau of Investigation announced that it had raided the Washington, D.C. house of Oleg Deripaska. He is a Russian oligarch and ally of Vladimir Putin, and the U.S. Treasury Department had sanctioned him in 2018.

Taken together, the two announcements showed diplomatic channels between Russia and NATO being cut back, while U.S. law enforcement acted against a sanctioned Russian businessman on American soil.
