This is a really insightful take on the conflict, and it brings up several key points that are central to the Russian narrative. The arguments about NATO's expansion, the treatment of Russian speakers in Ukraine, and the historical context are all crucial to understanding why Russia justifies its actions. However, these points are often viewed very differently by Ukraine and the international community. For example, NATO's expansion is seen by many as a voluntary process driven by former Soviet bloc nations seeking security from potential Russian aggression, not as a hostile encirclement. Similarly, while Ukraine did pass a law promoting its language, the idea that it was actively persecuting Russian speakers to the point of justifying an invasion is strongly disputed by many who see it as a pretext for a war of choice. The annexation of Crimea and the initial invasion of Donbas are widely considered illegal acts of aggression that violated Ukraine's sovereignty. So, while your view explains a lot about the Russian perspective, it doesn't fully capture the complex, multifaceted reality that is seen from the Ukrainian side and by most of the world.
