Here is, for example, a post by unabashed Russian nationalist, in support of the Russian invasion of Ukraine, blaming “Western Supremacist (…) miscreants” for the blood being spilled:

One of his previous posts is his analysis of the (then, upcoming) war, its context, and causes.
Of course, you need to take it with an open pit sized block of salt — eg he predicted that the Russia will most likely conquer Ukraine in less than a week. This, needless to say, turned to be laughably wrong, and makes rest of his analysis rather questionable.
The point is, however, that you are unlikely to see this sort of unabashed (indeed, proud) and undistorted Russian perspective elsewhere in western media sphere — indeed, I wouldn’t be surprised if this comment got downvoted for “spreading Russian propaganda”. Myself, I think it is extremely important to understand the perspective and motivation of the enemy, so that you can predict their movements and effectively prevent or resist them.
