Dont you think Russia it is quite powerfull and big to fight off one's territory so easily?
Fortunately we are not into a direct conflict against them like you are, that must be quite rough to deal with.
Do you seriously think so ??
Alas ... I have to disappoint you ...
1. Let's start simple. Big or great. Yes, geometrically - Russia is the largest country on our planet. But there is a small nuance. The real area suitable for the systematic residence of people (this is not only to put a building, but also infrastructure, industry, agricultural land, etc.), this is only (sit on a chair and hold on) 20% (TWENTY PERCENT of the total area) !!!!
2. Population. Officially, it is now talking about about 140 million people. But in reality - since 2010 the population census has not been translated. Why? I will not say. But for some reason, by this time (2010), the indicators of the quality of life in the Russian Federation slipped to the bottom - low fertility, high mortality, high growth rates of tuberculosis, AIDS, sexually transmitted diseases, alcoholism and drug addiction ... Most likely, like any totalitarian regime, Russia is such they try to hide information. It can be assumed that the real population is 80-90 million, only 2.5-3 times more than Ukraine
3. Army. I won't tell you a lot, just a few facts from reality. Russian weapons look good in advertising brochures, corrupt deals and propaganda cartoons! 2020-2021 - Russia is among the leaders of the military-industrial complex, sliding down. The destruction of corruption schemes and "controlled" governments has dramatically reduced the volume of arms sales. The failures of the vaunted S400 and similar systems in Syria, Libya, Azerbaijan - showed the true face of "a weapon that has no analogues in the world." It turned out it didn't work. It does not deliver the claimed effectiveness and does not fulfill its objectives. The poor quality of avionics and the production cycle put an end to the joint project with India in the development of a 5th generation fighter, which, by the way, has not yet entered the Russian army. Regular accidents with military aircraft in Russia are all a consequence of the expiration of Soviet equipment. Everything that was done later in the Russian Federation does not work as planned. Even strategic troops are experiencing constant problems with attempts to productively exploit new copies of nuclear weapons.
Well, a few words about the army as a whole. I probably would also consider her "strong" if I were not living in the country, and did not personally observe how these losers tried to "easily reach Kiev, in 2 days" , full-fledged units, with the latest weapons, ended in complete failure .. Despite the fact that in Ukraine in 2014-2015 there was almost no combat-ready army ("merit" of the fled traitor president), even volunteer battalions were enough to first stop the offensive of the "strongest army ", and then return a significant part of the captured territory. After that, hysteria began in Russia, all these Minsk agreements, which in fact stopped the liberation operation of the Ukrainian land from terrorists.
That is why now Russia is actively using local terrorists as cannon fodder, trying to slightly reduce the flow of coffins from Ukraine to Russia.
Yes, if this is not enough - just remember, but do you remember that over the past 30 years, the Russian army fought with someone who had at least a little bit of strength? Let me remind you against whom the "great army" fought - Moldova, Georgia, Ichkeria, Ukraine, civilians of Libya and Syria. But, for example, when Turkey calmly shot down Russian planes, Russia silently swallowed everything and kept silent. She didn't answer. When Azerbaijan and Turkey liberated the Azerbaijani lands from the Armenian-Russian aggression, Russia was silent and was afraid to utter a word so that only Turkey would not take more harsh measures.
In a word - read less, listen, watch the propaganda of the Kremlin storytellers, the reality is not the same as they say!
