Some have asked why Moscow is so concerned about Ukraine joining NATO when the Baltic countries that border Russia are already members. The answer is the Volgograd Gap, a stretch of land between the Black and Caspian seas which is strategically vital to Russia's survival.

From the Eastern border of Ukraine, it's only about 750 km to the shores of the Caspian. This terrain can easily be taken by an invading army using 🇺🇦 as a springboard. The Caucasus are so rich in oil and other resources that, to be ✂️ from it in wartime would mean 🇷🇺 sure defeat

Russia's fears of losing Ukraine and access to the Volgograd Gap aren't just based on speculation. During WW2, the Germans not only succeed in conquering 🇺🇦 but also a most made it to the Caspian sea, before they were stopped at Stalingrad (at the cost of 1.1 million Russians)!

So, while the world may condemn it, Russia feels that, based on her strategic needs and past aggressions, it's vital for Ukraine to remain in her sphere of influence. Moscow believes this so strongly that they are willing to take the risk so as to prevent a future Stalingrad.

For those who are asking, the clip about Ukraine is a video by the Youtube channel @CaspianReport from last Spring. Check out his channel, it's very informative news about geopolitics.
