The monument is still there and I never heard Zelensky publicly denouncing Stepan Bandera. The Russian language was officially banned in Ukraine well before the military operation.
I know even USA would not be able to get away with this. But the difference is that contrary to the Ukraine USA actually has statemanship competencies and would never ever ban say Spanish language or any other language for that matter.
The Russian language was never banned in Ukraine. Russian was removed from the school curriculum, but about 40% of Ukrainians continued to speak Russian both at home and outside home, including in public places like work, army, shops, markets, etc. Their children also spoke Russian at home, but spoke Ukrainian in school. Moreover, Ukrainian-speaking Ukrainians, of whom a very high percentage are absolutely fluent (at the native level) in Russian, switch to Russian without any issues to accommodate the people who speak Russian to them. At least, that's how it was before Putin started this war with Ukraine on February 24, 2022. Now even Russian-speaking Ukrainians are switching to Ukrainian at home (if they can) or learning Ukrainian so that not to speak the language of the Russian occupiers. This is what's Putler's war has done to the status of the Russian language in Ukraine. Once Ukraine wins this war, the Russian language will be hated in Ukraine even by the native speakers of Russian, just like I (a native speaker of Russian) now hate this language and refuse to speak it.
How many public schools teach Ukrainian in Russia as a foreign language or teach other subjects in Ukrainian? The answer is, "Exactly Zero". There are dozens of millions of ethnic Ukrainians who live in Russia. Zelensky always said that he would open public schools teaching in Russian if Russia opened public schools teaching in Ukrainian - one for one. He has the same parity conditions for other minority languages, such as Hungarian, Romanian, Polish, etc. Hungarians are also screaming about Zelensky having removed Hungrarian from the school curriculum in the areas of Ukraine that abut Hungary. They also refuse to open Ukrainian schools in Hungary.
Those who claim Russian was banned in Ukraine do not understand the subject at hand and are swallowing Putin's propaganda. Even today some Ukrainian army units speak exclusively Russian both in battle and at rest because the majority of soldiers in these units are native speakers of Russian. No one forbids anyone in Ukraine to speak any language, be it Mandarin, Spanish, English, French, Hungarian, Romanian, or Russian.
Stepan Bandera is a hero of the Ukrainian resistance to the Nazis and to the communists. He spent most of WWII in a Nazi concentration camp imprisoned by the Nazis for his resistance. The fact that commies and Russian nationalists hate him doesn't make him a bad guy, especially for the Ukrainians.
Additionally, Bandera is not implicated in the atrocities against the Jews in Ukraine as the Russians claim. OUN - Organization of Ukrainian Nationalists - had several factions. One faction was under the command of Bandera until he was arrested by the Nazis. Members of other factions of OUN - not under Bandera's command - did commit atrocities against the Jews especially in Belarus, but Bandera's faction never did. Moreover, the Bandera's faction of OUN had many Jewish members in it.
There is nothing for Zelensky (a Jew) to apologize to Putler (a fascist) for, and there is nothing that should compel Zelensky to denounce Stepan Bandera even if he may not particularly like him personally. Stepan Bandera is a national hero for many Christian Ukrainians, and now with the atrocities that the Russians have been committing in Ukraine, Stepan Bandera is a national symbol for a much higher percentage of Ukrainians than before Putler's war. The result of this war by the fascist Russia against Ukraine will be that Stepan Bandera will show up on the Ukrainian money, and Russian will die out in Ukraine completely because every patriotic Ukrainian - be he Ukrainian or Russian speaking - will refuse to speak the language of the Russian enemy.
