It is interesting to compare the German Wikipedia and the English Wikipedia articles on him – both cite some of the same sources, but German Wikipedia presents it as conclusive "he's a Nazi", the English Wikipedia article says "sources X, Y, Z have alleged he is a Nazi due to reasons P, Q, R", but leaves it up to the reader to decide if those sources and their reasons are convincing.
Also, "88 = Heil Hitler" doesn't make a lot of sense in Russian, since H is not the 8th letter of the Russian alphabet (it is Ж, normally transliterated as zh), and "Heil Hitler" in Russian is хайль гитлер – х is the 20th letter of the Russian alphabet not the 8th.
