If Ukraine falls, what’s stopping Putin from stopping there? EU has lived this movie before; an “Iron Curtain” will descend across Europe AGAIN. That is KGB officer Putin’s goal, to Make Mother Russia Great Again.
As I pointed out, most of the world is not on your page.
Have you ever wondered why?
Furthermore, the media, politicians and other vermin endlessly say and repeat that Russia can barely advance a couple of kilometers, that they're finished, etc., at the same time they say and repeat they'll reach Lisbon. Some bipolarity disorder?
So, where will they go? Their entire western flank is NATO, 30+ armies. Or is this organization so weak, and/or useless in its theoretical commitments?
On the other hand, I doubt Russia is interested in all of Ukraine. Certainly not the westernmost regions, for many reasons. Those would be left as a problem for the European Union.
And anyway, this announcement has such a low PR level that it's embarrassing, as others have commented.
