This is a very analytical essay regarding the situation in Ukraine. After a discussion of recent events, the author suggests three possible scenarios with the following ultimate outcomes:
1) nuclear war in Eurasia
2) China emerging as single world superpower
3) USA splitting into four separate countries
I don't agree that any of these scenarios are likely, but they could be realistic worst-case scenarios that could unfold should the USA react stupidly to events in Ukraine.
Without taking sides and labeling who is on the right side of history at present, we would like to state the possible effects of the new split (along Dnieper River) on the future of Eurasia and rest of the world. Strategically Russia may need more space to defend and manage the acquired peninsula of Crimea, that means further expansion towards north and North West of Crimea; politically, Dnieper River with bulk of Russian speaking population living along its eastern side becomes a natural barrier on which the new Russian border could rest.
