I haven't seen assassinations of important western figures, loads of Russians got liquidated though. If this wasn't a play a lot of heads of industry/hedge funds/banks would have rolled on our side.

There would have been a serious increase in terrorist attacks, that didn't happen either.

Heck they didn't even bother cutting underwater internet cables.

Now I'm certain we are being monitored, but I doubt they are that good to stop a nation state that has been doing subversive stuff since their inception.
