I'm not sure about that, actually.
The question you have to ask is WHY Putin picked this moment to go to war over a conflict he has been having with the Ukraine since 2014. The separatists were pretty firmly in control in the Donbass and his forces control the Crimea. He had a diplomatic path to resolved these issues through the Minsk Accords.
Then you look at the political situation in Russia. The dissident movement is growing, there's discontent over the economy and Putin's handling of Covid (Russia only trails the US, Brazil and India in the number of Covid Deaths).
A war might be just the big distracting thing he needs. Worked for Stalin.
Didn't work so well for Nicholas II.
