Okay, heard me out!
Do you know?, that the "Z" symbol those invading forces wearing is actually an "S"? And its literally means a Stalin mafia?, -as it at certain point become they symbol. And they origins, they roots, going as far back in history, to the bandits group that for centuries terrorize Siberia spreading onto entire world. Eventually they join together, to becoming a mafia like crime syndicate, on purpose causing/ brewing conflicts, crime all around world including word war one, two and cold one.
They former mafia boss was Stalin, who with his gang was robing banks, until he managed to kidnap entire countries. Then his (as stories go) illegitimate son, replaced certain secret service operative, taking his life and name, to do his revenge against society. Lie about promise of cleansing corruption from state he do exact opposite. Through backstabbing, corruption and high treason, once again the countries were kidnapped, and doing that he secure its place as a Stalin's mafia boss.
Legends says, that when his insane bed girlfriend, seduced him, to do his special military operation. He dint realized that the corruption, lies and injustice he spreed, soaked through all layers of society. She died with his hands on her neck.
His mostly illiterate brutes minions were too hasty to repaint the official federation army symbols onto the Z, faking the impression that everybody are member of Stalin's mafia. So the defender dint fight the Russian army, they fought bandits. Yet the main reason was to soak bullets as they will put away that marking to hide from justice.
This all happened because during partial break out of Soviet union, the Russian communism had been not crushed the same way and precision as fascism. So mafia retreated into shadows, waited, strike back and screw everything.
But, there is possible solution: People of Federation shall stop pretending to be pushovers and take justice to they own hands.
Its so easy to give to police a simple order to bring Z bandits, the Stalin's mafia, its supporters and collaborators; to the justice: (Warm or Cold.) Yet that boss claiming, that if he will go down, he will drag everybody down with him. The blackmailing stash and the list are prof. A golden bridge for the criminalized victims is needed to break even that illusion, to offer them opportunity to get out, to prove, they are not a mafia trash.
Also economic need to change from Neo Feudalism. There is question of kidnapped and refugees, they need to be returned to they homes. Adopting law codex of union will be instant fix to many problem, launching reformation in every sector, aiming to legally fulfill conditions for joining union and military alliance. After that, disbanding of soviet union, going by name of federation, can be finally completed. Yet we shall never forget about Z bandits and they centuries long wrongdoings.
So, do you think, the Stalinist will just sits and do nothing, as the justice trying to reach them?
