They definitely think of Finland, Baltics, Poland as their "lost territories". They openly talk about that in state TV discussion shows every week.

But there is also old Russian hardcore imperialist idea about "empire from Vladivostok to Lisbon" (although Chinese don't like that idea definitely, as Vladivostok is old Chinese town, taken from them in 19th century).

Why? Because putin wants to rule the world?
I think it is the usa who want to rule the world.
Russia wants a multipolar world.
America will not stop to try to invade every country on earth. Same old story.

There will not be peace in Europe until Russia is defeated. If Ukraine loses, Russia will not stop there.
