Yeah they're nazi shits, but they are also ultranationalist fanatics who say they are ready die for their country. Putin and gang intend to invade. Tight spot. What are the options here?

A: Kick them out and persecute them : resources allocated elsewhere, risk of great loss from the invading russians.

B: Don't let them participate : not great, pretty much sheltering nazis behind lines.

C: Let the ultranationalist fanatics die for their country like they want to.
