1) In Ukraine the phenomenon is much more widespread and institutionalized. E.g. neo-Nazi units integrated into the official armed forces of Ukraine. Major streets named after a leading local collaborator of the Third Reich. Municipality officials in the capital city of Kiev publicly glorifying said leader. No equivalent anywhere else.
2) In Ukraine it is directly state sponsored. Again no equivalent elsewhere.
3) The Ukrainian regime's foreign patrons, i.e. the USA and Isra"el", as well as globalist oligarchs who funded the CIA-engineered "colored revolutions" in Ukraine (Soros etc) are the root cause behind this "nazification" of Ukrainian society and government institutions, which they've been promoting in a calculated and deliberate manner, because historically the Ukrainian far right has been marked by a violently anti-Russian orientation. This is used by NATO to turn Ukraine into a geopolitical tool for its plots and aggressive bullying policies against the Russian Federation on its western frontier.
So Ukraine definitely stands out in this regard, and can impossibly be assimilated to other countries, where neo-Nazi currents are on the contrary marginalized by the powers to be, and play no such significant role in society and politics.
