Hours back Russia have closed its skies for 27 countries. Already it has closed the skies for Bulgaria, Poland and Czech Republic. Now it looks like Germany, France and more European countries added to the list. Earlier European countries banned Russian flights for specific time period. Now Russia is making the same decision as the countries that closed skies for Russian flights. This is going to make the economy even worse. For now we can't predict what is gonna happen with both the countries.
That number went to 36+ later on, and also Japan joined the nations that is keeping all the Russian central bank assets as well. So basically there are about %40+ of Russian money held and not given back to them at this point. You may see this as "unjust" if you are a Russian or support Russia, but you shouldn't have bombed civilians if that was the case.
If Russia wants to "protect its borders from Europe" which makes no sense, I would love to have borders with them, not like we could expect Europe to go into war with Russia first, only retaliate but even assuming that, then just start doing the exact thing to Europe, instead of attacking and killing civilians. You are not sure about Ukraine getting nukes or not? Put plenty on Belarus, you are worried about Turkey?
Put some in Checnya and Georgia or whatever else they have, hell even Azerbaijan which is known to be friendly with turkey, but would love nukes because of Armenia. All in all just do what they do, not kill innocent civilians.
