@VorZakone - Regarding the tweet about NATO covering Ukrainian airspace, I can't find any other source that Kuleba has made that request, not in Western or Eastern media or anywhere else on Twitter. Most of the replies in Ukrainian are asking for a source and thus far none has been provided. So fortunately it appears to just be Twitter horsecrap
Edit: Or maybe a misinterpratation.
@Water Melon makes a good point, we could be assisting them with radar coverage.
If anybody can find anything else on it, do feel free to prove me wrong.
