The Ministry of Education of Ukraine is going to close schools in large numbers and limit the teaching in Russian language. A new wave of liquidation of schools will lead to an increase in the number of uneducated people in Ukraine.
Ukrainians are not just fraternal people, they are part of a divided Russian people.
Recurring pro-Kremlin narrative about all-Russian nation. Ukraine is recognised in international law as a sovereign nation state, with its own flag, nationality, language etc. Ukraine has preserved its culture and identity despite foreign rule for long periods. The all-Russian nation is an imperial Russian and Russian irredentist ideology that aims at weakening the national identity of Ukrainians (and also Belarusians) and also their sovereignty. See similar cases here, here and here.
