I’m not sure how territorial\political losses or economical decline would make russians frustrated rn. With a total grasp on local media, Tzar can easily put a blame on other states and for his followers it works. They do sell the myth of capturing others is the way to go, and that it needs some sacrifices.
I am not saying it's a magical solution. But their only hope for a better life (democracy, government respecting their rights and not being able to just randomly kill people, addressing corruption) is them understanding that their dreams of empire are over and that they will be treated as they treat others (no visiting Europe). They can keep playing the victim, it's all up to them.
I think you’ve been caught in a trap of thinking russian commoners are somehow different to others. Vatniks aren’t an unique occasion, and it seems a lot of countries are vulnerable to have them, especially if authporitarian states put effort to nurture a culture of useful idiots somewhere else like Russia does in bordering states.
That's where I will strongly disagree with you. I will even go as far as saying this sort of attitude (and variants) of it is a key enabler of russian degeneracy.
I've lived in several countries in North American, Europe and Asia (several years each) and you're right there are "vatniks" everywhere. However, what is unique about russian chauvinism is 1. It's brutality and self-important backwardness. 2. The level to which it is universal across any and all demographic group; chauvinism and genocidal imperialism is the defining aspect of russian culture. That is not true for all countries.
Russians are still stuck in an 18th century colonial mindset. They reflexively gravitate towards taking land and forcing occupied people to become russian. While the rest of the world has largely moved on more efficient forms of geolpolitcal influence. And this is true for North America, Europe, Latin America, Asia and Africa.
Support for genocidal imperialism has a strong majority across all demographic. You can slice the population by age, education, rural vs urban, income, federal district and still get a strong majority support for genocidal imperialism. Different quantitative methodologies, qualitative research, longitudinal studies; it all leads to dark, black hole of cruel and crude imperialistic mindset that dominates all priorities (even the well being of their own children).
This is not the case for all countries. There is been a lot of news about Hindu-nationalism in India. But even in India (a country much poorer and less education than russia), there is a modicum of internal cultural dynamism. You have the muslim minority. People in the south have their own language and culture. The Bengalis in the west have linguistic and kinship ties with their muslim cousins in Bangladesh.
Or consider the US, you have a lot of "vatniks" there too (I always found it entertaining how such a large portion of American are "experts" on constitutional law), but you still have some sort of internal sociopolitical dynamism. I believe US leadership has apologized for genocide against the native American population? Have you ever heard of any apology russians about the countless genocides they implemented over just the last 100 years?
And the West continues to ignore the russians' deep rooted and near universal commitment to genocidal imperialism. The West continue to coddle the russians with their child-like fairy tales of the population not supporting putin and genocidal imperialism.
They need to understand that won't be able to play dumb. They can play the victims and say that "you're playing into putins hands" or "you're discriminating against russians"; or they can start thinking on what they need to do change things. It's their choice.
