The correct solution is for Russia, the successor state to the USSR, to renounce Stalin’s 1945 annexations and to give Western Ukraine back to Poland (or Austria).
Poland doesn’t want it.
At best Poland would like to be able to visit Lwow/ Lviv, a Polish heritage site.
This would be analogous to Wroclaw/ Breslau. Germans can visit, live and work in Wroclaw today.
