It is is essential for Ukraine to rid itself of Nazis in order for stabilisation. Nationalism and neo-nazism, fraught with anti-semitism have to be eliminated for the country to be healthy.
This disinformation message is consistent with pro-Kremlin narrative about Ukraine and Nazis.
Under denazification, a process and a set of measures is meant to rid societies in Germany, Austria, and other European countries of Nazist ideology. However, neither Ukraine's culture nor press nor judiciary nor politics are marked with this ideology.
Furthermore, the fact that Volodymyr Zelensky who recently won Ukraine's presidential election by landslide is of Jewish ancestry, disproves the allegation about wide-spread neo-Nazism fraught with anti-Semitism in Ukraine.
