It'll merely pad some of the damage, not all of it, and not for the majority of the Russian population. It also takes a long time (in the context of a war) to train up effective new soldiers to replace dead soldiers and to replace large amounts of destroyed hardware, particularly given Russia's meager manufacturing capabilities. Putin likely gets one shot at taking Ukraine (and that's right now), regardless of the inbound oil money. It'll take a decade of bountiful oil money for Russia's military to recover from this disaster.
