It's more than a loose alignment lol. Members of the Azov Regiment and National Corps are pretty integral to the broader pro-White movement in Ukraine.
That's far from the only reason the Dissident Right is interested in Ukraine, though. The big reason (at least for me) is that the government doesn't really interfere with /ourguys/ organizing at the same level they do in most other European countries. Plus, society as a whole is generally more accepting of our ideas than even other Eastern European countries, and the laws restricting our ability to speak our minds are not nearly as severe as they are elsewhere in Europe.
I don't want to oversell it or make it sound like there are no downsides, but when you look at how far Europe as a whole has degenerated socially, politically, spiritually, etc, countries like Ukraine look like paradise by comparison.
