From my first hand experience when I visited last year, nearly everyone I spoke to had a hard time acknowledging there was anything wrong with what they saw as Russia reclaiming land that was rightfully theirs. There was often outright admiration for Putin for being brave enough to put the interest of his nation first and telling the West to go swivel.
No coincidence that India has similar feelings towards several of its own neighbours and parts of Kashmir are not too dissimilar to Crimea.
The reaction would be very different if China ever did the same in Taiwan though, because… reasons.
