You should listen to their plan.

They are explicitly expecting a major political re-alignment, and they want to have enough radicalized National Socialists and veterans to be a significant and established political force in Ukraine so they can take control in the chaos. They literally believe that in the political fragmentation, they can use their militants to seize power. Militants they are creating in this war. It is only after that point that they will "clean" Ukraine. Their words.

They were bringing up the potential break-up of Russia, and exploiting that opportunity to basically try and turn Ukraine into a massive regional power. But that's kind of where their delusions of grandeur take over.

The National Socialists are quite a pie-in-the-sky bunch, but they aren't kidding when they say they are trying to achieve it. They'll take Jewish money to kill Russians, if it gives them enough political capital to kill Jews later. They don't care, it's a ruthless quest for power.
