According to the Russian military, it is known for a long time that Russia is the main enemy for the United States. The USA has been preparing for a war with Russia since 1945, when it adopted Hitler’s initiative of hatred towards Russia. In 1945, the US and UK developed the “Unthinkable” plan, which assumed the continuation of WWII against Russia with support of the re-armed Wehrmacht troops.
Moscow Rus’ is torn apart between gathering the territories, isolationism, Western pressure, and an attempt to turn East. Ukrainian Rus’ and Belarusian Rus’ are turning into the frontier oscillating between different civilizations and even into the real war frontier as it happened in Donbas.
Lately the ideology of unified Russian people consisting of Belarusians, Russians, and Ukrainians is losing its popularity. A new Russian identity should deal with this new reality about three Russian states and three Russian political nations. Controversies among them can only be overcome when they have a common goal, that is perceiving themselves as one civilisation. Ukraine is not lost as long as Belarus stays with Russia. In case Belarus is weakened and falls into the situation similar to present-time Ukraine, the Russian civilisation will be shaken and the existence of Russia itself will be put in question.
Recurring pro-Kremlin narrative about all-Russian nation and Russian world / civilization. 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.
