Yes, it is blindingly obvious, as you said. However, you need to zoom out and look at the bigger picture. Why did Russia start this SMO? I don’t believe that it’s because they want to have more territory. After all, have you seen a map recently? Are you aware how big a country Russia is in terms of land mass?
I have listened to real experts, professors at highly acclaimed western and eastern universities, who have explained how and why NATO’s expansion eastwards is a security threat to Russia and in spite of Russia’s warnings, they (NATO) ignore it and continue to do so. This, in their (the experts) opinion is why Russia is compelled to act. I find their reasons compelling and natural. We see this playing out in Asia as well but fortunately, the Chinese, with their thousands of years of civilisation, will achieve a better result.
