For me, I personally think Russia’s goal with Ukraine is to restore the culture, removing woke ideologies.
We can also notice this in recent Decree:
"President Vladimir Putin signed a decree allowing foreign citizens and stateless individuals to apply for temporary residency in the country if they share “traditional Russian spiritual and moral values,” even in cases when a person does not speak Russian.
The decree states that those who oppose the “destructive neoliberal ideological agenda” in their home country can seek “humanitarian support” from the Russian authorities by applying for a temporary residence permit."
I mean, think about this, if their goal is land mass, it doesn’t make any sense. Russia is the largest country with a population of 140Million. By any means they are similar to Australia. If we go by resource, Russia has the largest natural resources in the world.
So the goal is either preserving Tradition and culture or securing pipelines.
