we will have all 3 reasons in place in the summer , but this times the protects will be anti - colonial
One can't exclude any possibility occurring in this ridiculous war - but personally I do not see a "revolt" scenario of dangerous proportions to happen in Russia.
Try and place yourself into the shoes of an average Russian (it is those people who suffer most in a war - economically and on the human side)
Presently the majority of Russia's general population are supportive of this war due to holding certain beliefs.
Just take WW2 and the prevailing mindset of the general German population at the time. - governed and controlled by a ruthless autocratic system:
Yes they were desperate in view of the Allied bombings, bringing added death-toll and destruction to them - towards which they rightfully felt defenseless and as such questing (very silently for themselves) the governments competence. Revolting? protesting? no way - such persons are send to Dachau because they are defeatists and traitors to the people. Anyway we are getting wonder-weapons that will turn the tide.
Did Hitler cause the war? off course not - it was the English, French, the international Jew lobby controlling the USA, who wanted to prevent Germany's new rise - preparing to attack us/ hell, the English and French even declared war onto us, not we onto them, thus causing death, losses and endless misery amongst every German family.
Okay attacking the Soviet-union wasn't seen as an easy challenge - many (very silently for themselves) even questioned a probable positive outcome - but better we attack them before inevitably Stalin will attack us anyway - right?
Hitler and his hardcore-Nazi and SS leader buddies never accepted or even considered unconditional surrendered - even though around 80% of German territory had been occupied/conquered and controlled by the Allies already.
According to a relative of mine who served in that war; sorry, but that was his honest and true conviction:
It was only the followup government (headed by a spineless Wehrmacht officer and influenced by people of economic greed) that acquitted towards unconditional surrender. And even that government had not come about via protests - but had been simply installed by it's predecessor who had committed a hero's death a week earlier.
You think that any larger proportion of the German population cried out or thought for themselves,"stop this war in Russia" - our sons are dying there now already since 1,2,3... years?
Certainly not, they were simply praying/hoping for a German victory to finally end this war - a war that had been brought/forced upon them by all the other countries.
