I think Russia's strategic objectives are as follows
-Build up enough modern combat power to serve as a "credible deterant" against aggression. This will prevent Russia from being pressured by a Western threat of a massive and unstoppable strike.
- Be able to advance Russian interests in the world . Russia was terribley embarassed when they were powerless to assist Serbia in Kosovo. Russian planners then said "never again". The Russians dont have to be able to beat the West, just make it think twice... or even three times before harming Russian interests. China has the same strategy.
