I recommend a 2015 – but still quite relevant – book on the international political situation in Ukraine by Menon and Rumer.* The authors provide a very accessible background on the history of Ukraine, and the evolution of contemporary relationships both within the country and internationally, with Russia, the US, and Germany, France, the UK and the EU. They help clarify a number of over-simplified views, such as any sharp East-West divide within the nation. They describe the recent crisis with Russia, in relation to Crimea and the Luhansk-Donetsk region in Eastern Ukraine, concluding that all of the supporters of Ukraine, such as the US and EU, see their own self-interest at stake in how this evolves, but not strongly enough to intervene or take a more active role, ‘leaving Ukraine to tackle its challenges largely on its own’ (p. 155). And that is where things stand today.
If you would like to better understand the political dynamics of this conflict in Ukraine, I recommend Menon and Rumer’s book. In hindsight, they were exactly right in their view of the prospects, and remain on target.
