There is talk about Russia making access to their friends in Hungary and Serbia to free them up from US/NATO/EU treachery. I think that would require all of Ukraine? That's what I would like to see come about, otherwise they are really screwed.
They connect to the West/South part of Ukraine (Trans Carpathia) which is already unhappy with the Kiev Regime.
That is mostly a heavily forested area, and easily defended.
Slovakia connects there as well.
So those countries would no longer be landlocked by EU controlled states.
