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.
Absolutely right, lesson of the history is that no country ever defeated Russia in winter , this is their strength and they use it wisely , even Hitler was not defeated by Russia but winter. The 2nd strength of Russia is its huge gas reserves and European depend on it to run their Industrial complexes and maintain heating system of their homes. I am still optimistic that this conflict will not turn into any major war and eventually it will be resolved through negotiations.
