Somebody already told that, but when one looks to Russia's history, they'll see that, the goal is to get bigger and bigger for centuries. They want access to warmer waters (i.e. Mediterranean waters) for at least two centuries now.

So, there's no fake victory, and there's no stopping for them. Also, this is not related to Putin only. Russia is one of the countries which have a stable strategy for at least a century, and they just want to make their goals a reality.
