For all of what passes for Western "intelligentsia" carping on Putin as a Stalin remix, the "sick Russian bear" and stupidities of the same ilk, a strategy lesson is evolving.

Accrue your potential. Then retake the initiative. Strike only when the right convergence presents itself. And then the "tactician" on the other side, already blinded because he does not respect you, will be left clueless, wondering what hit him.
