DISINFO: Belarusians and Ukrainians are part of the Russian people
SUMMARY
The Russian people consist of Belarusians, small Russians [Ukrainians] and Great Russians. Common characteristics of the Russian people are a strong sense of justice and search for the truth.
RESPONSE
The "all-Russian nation" is an imperial Russian and Russian irredentist ideology that is a favoured pro-Kremlin narrative aimed at weakening the national identity of Belarusians and Ukrainians as well as their sovereignty.
Ukraine and Belarus are well-defined nation-states with a long history; both nations preserved language, literature and identity, despite foreign rule for long periods.
Other examples of pro-Kremlin disinformation outlets' attempts to question the Ukrainian and Belarusian nations can be seen here, here and here.
