Ukraine is headed in the direction of Yugoslavia.
The EU & US broke Ukraine. They were going to have elections next year. No one was advocating splitting the country.
EU & US gave billions of dollars to the “opposition”, and lo and behold, armed neo-Nazi thugs with weapons seized power in Kiev. First things the new guys did was ban other languages (including Russian and Hungarian, note that Russia is spoken by about 30% of the population as its primary tongue) and legalize the use of Nazi symbols.
Crimea never belonged to Ukraine until Ukrainian Nikita Krushchev gave it as a gift in the interests of brotherly love, redrawing the internal Soviet administrative boundary. The idea that the EU & US could use neo-Nazi Bandera-OUN-types to seize power and the country would stay as one was fantasy and rank stupidity.
We need to stay OUT.
