Well, I'd start by reading a better quality, more factually driven news source that isn't so hyperbolic.
Russia has been sabre rattling for years now, even pre Ukraine. We are arguably already in a third world war, but it looks different to how we may have imagined.
The strategy for Russia isn't to go West, but to go North West. Russia wants the seas to the North, China the South. So, Scotland is in peril, as are the Nord8c states.
This has been so for a good decade or more. What we're seeing now is an amplification of that action.
I wouldn't pay attention to right wing gutter tabloids. What they're reporting on is a re-militrification of Europe, largely in response to the current US Administration's shift away from Nato values and the post WW II agreement between the US, UK, and Europe. So it's just a , correct, response to a changing geopolitical landscape.
Go have a brew, read Bella.
