Once again you show yourself to be utterly misinformed. Russian currency was incredibly undervalued in the west creating an impression of a much smaller economy than it really is. In practice, the economy is actually bigger than that of Germany in real terms.

There is absolutely zero evidence for the statement that the current sanctions are more than Russia planned for. It's also absolutely ridiculous to think that Russia went to war without considering what the worst case outcomes would be. Would love to see the reference to Putin actually saying what you're claiming he said.

You have an overinflated idea of the role the west plays in the world, and in the coming months you're going to have to come to grips with reality.
