On the other hand they praise Putin for leading the fight against the liberal west and choose to see the Ukrainian war in that perspective, fully drinking the Kremlin cool aid.
They don't think it but their actions are saying the opposite. Otherwise a tankie like Edy Ongaro wouldn't have traveled 1000 km to go die in Donbass trying to help Russian kill the bad fascist Ukrainians
Or another tankie like Jorit would have understood the irony of painting a murales "against the Ukrainian atrocities" on a residential complex destroyed by the Russian army
