Galicia, Volhynia, and Eastern Ruthenia SHOULD secede from Ukraine and join the EU, and NATO if they wish.
A lot of central and eastern european borders are FUBAR. I think it’s better to let sleeping dogs lie than start some more shooting wars over them.
Interesting that Zhirinovsky did not offer Vilnius to Poland. I guess they plan on keeping that one!
But you don't get to choose.
