I'm not surprised by this, words change over time and meaning can vary, even between closely related languages. Take Stout for example, in Dutch it means naughty, in English it means strong, among other things. So a mistranslation is very likely.
As for the social unrest I just read that the Duma is proposing a new law making it illegal to refuse to fight, punishable by up to 10 years in prison. I'm sure that will quell the unrest.
