By all accounts, Vlad the Invader's Russian government is built on a culture of corruption, at a level of corruption many a third world country would blush over.
Ukraine's corruption is also a serious matter, in wartime corruption is an issue of life, death and treason.
The difference between Russia and Ukraine is that Ukrainians are publicly working to expose and eliminate corruption, whereas in Vlad's Russia, corruption continues as usual, regardless even of its effects on Vlad's Invasion of Ukraine.
