These first months of this War have shown us quite a lot about Russia Military Capabilities.
And so far, they have failed to impress.
They outnumber and outgun the Ukrainians massivley on the ground and have total superiority in the air.
Despite this they have failed to take key targets.
In fact it looks like a repeat of their misguided attempt to conquer Afghanistan.
And IF by some misguided chance Russia decides to mount the same sort of invasion against, particularly, Sweden, then the majortity of the European Nations are going to have to join in, whether or not these two have joined Nato.
Both are EU Countries, and while this is not a Military organisation, it does mean strong ties and one flag.
The level of support, for example in airpower, will make the Military help, grudgingly given to Ukraine look petty.
And there will be Naval support too.
The Russian Navy is said to be rather dilapidated, for the most part.
I suspect that this announcement is for 'home consumption'.
They haven't established air superiority.
