The rich are going to care about their hoards, not about the "special military operation."

Then why is Ukraine losing?

The Russian capitalists did hate this. This war is incredibly unpopular among Russian capitalists.

What PolandIsAStateOfMind is saying is that among those who were on the west's side while still living within the Russian economic system, more than before will flip to embracing Russian finance, because their money will be irretrievable lost to western thievery. As long as the money hasn't been spent, there's a possibility that they'll stick to liberal principles of private property. That means returning the money after the war. It's naïve because the west already stole Afghanistan's money as retaliation for Afghanistan winning the war against the USA.

But some Russian capitalists might've been holding out upon the belief that the west's racism was why they would steal Afghanistan's money, but not do the same to white and west-worshipping capitalists oppressed by Russia's state-oriented actions.

If Russian investors weren’t put off by having assets frozen when Russia invaded Ukraine in 2022

They already were, why they would even put more money there when they are getting frozen, but as long as their funds are only frozen, they could still have hope that the entire issue gonna get resolved one day and they will get it back. If the money get confiscated, that's entire another situation.

Russia’s GDP is dwarfed by the West

Muh GDP!
