DISINFO: Ukraine is a part of "Russian World"
When we say ‘schism’, we all speak not of the Church schism per se, but of the schism in the Ukrainian society, the schism in the Russian world, which Ukraine is a part of, if you will.
Ukraine is recognised in international law as a sovereign nation state, with its own flag, nationality, language etc. "Russian World" is a narrative created by the Kremlin for its own political purpose. Ukraine is currently defending itself from Russian aggression on its territory, see e.g. http://euvsdisinfo.eu/report/russian-spring-civil-war-was-unleashed-in-east-of-ukraine-by-little-nazis-in-kyiv-after-a-coup/
