NATO is not supplying anything to Ukraine. I don’t think you understand what NATO actually is. If Ukraine was actually part of NATO, Russia would have to immediately back off because that would add the nuclear deterrent Ukraine needs to stop the invasion, because NATO is a nuclear alliance. If any one country is attacked, all the other countries would retaliate. That is why Zelenskyy wanted Ukraine to be part of NATO and why he said that if Ukraine were to be allowed to join he would resign as president immediately. However they are continually rebuffed because seven nations, including the United States and Germany, are blocking their accession to NATO.
Individual nations like Poland who’ve seen this sort of thing happen before and determined to help fight it.
You should learn to make the distinction between a NATO allied nation and NATO itself. Individual countries are still free to do what they like in terms of international intelligence and weapon sales.
