Maybe, maybe not. The doolittle raid on japan pissed off the japanese for attacking their capital. It was a huge morale booster for the Americans and had the opposite effect on the japanese who now knew their homeland was not safe.
Not that putin cares about public opinion but the mood of the russian people might change if they start to feel the war's effects at home.
What happened in the US when 9/11 occurred? It was one of the few moments in the past decades where the country was united, put aside differences and was patriotic.
I suspect Russians that were on the fence will rally to support the cause now.
