Pair the narrative of the smaller country being invaded by the belligerent dictator next door with (in my case) a country where Russia is already unpopular due to various assassinations, sabre-rattling, and so on, its not hard to understand the current balance of
In the UK the mainstream (serious) news has been fairly reliant on reporting based on estimated troop movements illustrated by video so there hasn't been too much potential for egregious nonsense.
In my obviously biased view the thing that worries me is actually people (knowingly, twitter promotes a fairly distorted presentation of ones true feelings) swallowing Russian propaganda hook line and sinker out of a fairly boring contrarianism.
It is easy to imagine the debates in the neutral (or less than neutral) countries of past historical conflicts - you can make your own mind up about how those debates would go, but this conflict (paired with such easy access to differing opinion) seems to be a great source of material.
Contrarianism is often a very important thing to have in society, make no mistake, but many would benefit (and perhaps internally do, who knows) from being contrarian against their own beliefs, even just for a little time a day - this goes for both sides of this conflict although I won't pussyfoot by saying that both sides are in some way the same.
