I'm sure historically a lot of wars have been land grabs, but WW2 was not one of them. There were a lot of underlying sources of conflict there. And while yes, if the invaders agree to leave then most wars would end, there's often an underlying unresolved source or sources of conflict that prevent that from happening. This is just Putin wanting to expand Russia's influence. It's essentially a conquest. If Ukraine were to give in to Russia's demands, another country would be the next victim on the list, and that would happen again and again until they were met with resistance.
So yes, you are correct that it's a war on paper but hopefully you get the point that I'm trying to make.
