It's the economy, stupid
The Soviet Union's collapse in 1991 was a combination of factors, including economic stagnation, political instability, and the inability of the centralized command economy to adapt to the changing world. Key contributors included a decline in living standards compared to the West, the cost of the arms race with the United States, and the emergence of nationalist movements within the Soviet republics.
The "nonsense" (bombing ukrainian civilians, hospitals, deportation of children etc.pp.) can only be stopped by Putin. And Ukraine WAS neutral before Putin started the wars in 2014 and 2022.
Why should Ukraine be a buffer zone? It's THEIR decision how the want to live and that they want to stay a democracy. Not Putins.
