It is obvious that some Russian neo-nazi groups or individuals adherent to neo-nazism found out that ideology of some Ukrainian neo-nazi groups is close to them, hence their collaboration with Ukrainian neo-nazi battalions like "Azov". Russian nationalists do not like Putin, base their ideology on pan-slavinism, here their sympathy for Ukrainian nationalism starts.
Ideological one fights for Ukraine cos , they represent Christian working class, many more fight for lugandon they are opportunists , mony+ social lifts . The first group have even Jewish support, Andrey Piantkovsky, Svoboda rádio. In Democratic countries even neo Nazis have their small places
Mostly they are those who deplored the end of the USSR and want to see the old USSR empire rebuilt. And Putin encourages them because that is what he wants. The breakup of the Soviet Union was something they wished had never happened.
