Putin choose winter because every country that ever fought the Russians failed because of the winter.Russia has all the gas and oil it needs to maintain a perpetual war machine and a nuclear arsenal to back it up if it ever fails.Russia are effectively undefeatable using military means.Also their people are more resilient to hardship than western societies so winter would prove harder on our soldiers and citizens because we are soft whereas they are hard muddafuddas.If we engage in war with Russia over Ukraine which is literally ran by neo nazis then Europe will be the first to fall and after that anything goes.
It's all fairy tales

1. You probably did not serve in the army, and do not understand how it all works? Winter is chosen only so that military equipment can move normally without getting stuck in mud and puddles. This is the main reason for choosing such a period for OFFENSIVE operations, when it is necessary to organize a guaranteed rapid movement of army units deep into the territory where military operations are planned to be conducted.
2. Of course there is oil and gas. But the economy itself is resource-based, backward, and objectively corresponds to the level of third world countries. Exactly the same economy that buried the USSR, and then Russia in 1998, when they then begged the whole world to give them at least some food. And oil and gas, at this time, has not gone away

3. People are not resistant to difficulties - if you look at the regions outside of Moscow or St. Petersburg, where it is totally difficult, you will see that these "heroic fighters with difficulties" are almost all totally drunken and marginalized beings. They just do not know how to deal with difficulties, to change something around them, they just sink to the bottom. You confused "fighting with difficulties" with "habits of a slave who lives at the bottom and has no right to change something."
4. Neo-Nazism, Nazism is just a hallmark of RASHISM. And his supporters in some countries, cultivating the Nazis, the Reichs and the "great Fuhrers" and other abominations. Or can you give a reasoned, verifiable, example about the heyday of neo-Nazis "managing" Ukraine?

)) Just a request - not hysterical Kremlin slogans, but facts, and do not run away from the answer, do not be silent, it will be very interesting to continue this topic!
