Well. I have read all your post up to the end and I must admit that you described the events quite correctly.
There's only one thing that should be stressed. What Russia did was not a waging of war against Ukraine but assissting Ukrainian separatists in their armed struggle against the new fascist regime in Kiev.
I believe that this was an honorable deed that was done by Russia but you say that Russia waged a war against Ukraine. Of course the new fascist regime in Kiev after Maidan was a regime that was going to convert Ukraine into anti Russia and the majority of people living in the east of Ukraine as well as Crimea did not want to obey the Kiev regime. That's why they decided to separate from Kiev and as a result of this the Kiev regime sent ATO forces to the east of Ukraine and ordered the bombing of the 2 breakaway provinces.
If there is a fascist regime in Ukraine, then why is the Russian-speaking population not oppressed there?
You again have incorrect information about the actions of the Ukrainian government and its people. The events of the end of 2013, which took place mainly on the Independence Square in Kyiv and were called the Revolution of Dignity, were exclusively directed against Yanukovych’s entourage, who abandoned Ukraine’s previously taken course of joining the European Union. It was because of this that people took to the streets in outrage. But since Putin saw that Ukraine would escape Russia’s control if it joined the European Union, he decided to forcefully turn Ukraine away from the European Union, and at the same time from possible accession to NATO in the distant future. But the Russians were practically indifferent to the pro-European positions of the Ukrainians. That’s why the Kremlin came up with the myth that Ukraine is becoming anti-Russian. Otherwise, the Kremlin would not have been able to mobilize Russians for war against Ukraine. The hostility towards Russians is now increasing only because Russian soldiers are now trying to destroy Ukraine and Ukrainians, and the remaining 70 percent of the Russian population still supports this war.
And now about the bombing of the “breakaway provinces”. Putin’s initial plan was to return the DPR and LPR to Ukraine after some time, but on the basis of autonomy, in which these pseudo-republics would have their own police, courts, army and representation in the legislative body of Ukraine - the Verkhovna Rada. If this happened, this autonomy with the full control of Russia would strictly prevent Ukraine from joining the European Union and NATO. But Ukraine, understanding this, could not accommodate such plans of the Kremlin. Then they decided that they would encourage Ukraine to make such a decision by constant shelling of Ukrainian territory from the demarcation line. For some time, understanding the essence of these provocative attacks, Kyiv did not give permission to the Ukrainian Armed Forces to return fire. But the soldiers at the demarcation line began to be indignant: they were under constant fire, unable to hit enemy firing points. Therefore, after some time, such permission was given.
And now about the shelling of the LPR and DPR, and in particular, Donetsk. You claim that from 2014 to 2022, Ukraine constantly bombed these territories, destroying cities and their populations. The positions of the Ukrainian Armed Forces near Avdeevka were only a few kilometers from the city of Donetsk and cannon artillery could freely reach there. What would have happened to Donetsk in eight years if all this time the Ukrainian Armed Forces had been constantly shelling and bombing it? Let me remind you: Russia is now turning large populated areas of Ukraine into ruins in just a couple of months. But even now there is no major destruction in Donetsk. From time to time, the Ukrainian Armed Forces only carry out targeted strikes against concentrations of enemy personnel and equipment. In addition, the Ukrainian Armed Forces could return Donetsk under its control many times over. Periodically, they drove into Donetsk in armored vehicles and noted the almost complete absence, not only of defense, but even of enemy troops. But if the Ukrainian Armed Forces had done this, then Donetsk would definitely have been turned into ruins, as Russia is now trying to do with the liberated Kherson.
