Writing of this thesis started back in 2021 – about one year before the full-scale Russian invasion in Ukraine. Initially, it was planned as a contribution to facilitation of Ukraine’s reintegration of those regions in Donetsk and Luhansk oblasts that had been occupied by Russia in 2014-2015. However, the focus had been shifted in February 2022, when I was taking cover in a shelter during Russia’s airstrike. Not surprisingly, a significant share of this paper was being written during missile attacks – except for the small breaks to play "Uno" with my nieces, cousin, and our new friends from the shelter. This work and opportunities that it, hopefully, opens are dedicated to men and women who have been fighting for Ukraine in combat, as well as to volunteers who have been helping them. For they are the ones who gave me the privilege to worry about this thesis at all.
