I'm most surprised that Western think-tanks wouldn't hire him. Seriously? Passing up a Russian patriot from Putin's security elite because they already have Russia Experts? Makes little sense to me.
Haven't stopped but really undermined it. War allowed EU to take action, clean up Russian intelligence networks etc. Before war it was politically difficult to be outright calling Russia an enemy or a threat so they had to play games.
Just because Kremlin decided to run this "special military operation" it doesn't mean they stopped their espionage in the rest of Europe.
