I think this guy paints a difference in thought that is not really there. Putin sees Ukraine neutrality and impotence as vital to Russia's security. No, he probably does not want to actually annex Ukraine, that would be a ball ache he doesn't need, but he would like it to behave like Belarus.

I think the real difference lies in whether one believes Ukraine deserves to decide its own path, or if it's forever doomed to be a chess piece on the board between spheres of influence, which seems to be the mindset both Putin and Trump are stuck in.
