Many places, as impulse has said, interviews, speeches, publications, public meetings, like this one for instance: "In the West, the prevailing narrative is that Russia initiated the war with its special military operation and is therefore the aggressor, so it is allowed to attack the Russian territory using Western weaponry. It is argued that Ukraine is merely defending itself, and is justified in doing so. I want to reiterate: Russia did not start the war. It was the Kiev regime that initiated hostilities, following the declaration of independence by residents of certain parts of Ukraine in accordance with international law, and continues to do so. If we do not recognise the right of these peoples to declare their independence, then this is indeed aggression. Those who have supported the Kiev regime’s war machine over the years are, therefore, accomplices to this aggression. Back in 2014, the residents of Donbass refused to surrender. Militia units stood their ground, repelled the punitive forces, and eventually pushed them back from Donetsk and Lugansk. We hoped this would bring those who initiated the violence to their senses. To halt the bloodshed, Russia made its customary appeals for negotiations. Talks began, involving Kiev and representatives of the Donbass republics, with the support of Russia, Germany, and France." https://mid.ru/en/foreign_policy/news/1957107/ It's a slog, but if you read this you will see that from Russia's perspective initially there were very limited war aims related to the Russian groups in the Donbass. Of course now Putin is considering taking all the Donbass, given the toll of blood Russia had to pay.
