According to Russia, even sending weapons is an act of war. It all has degrees. There is a clear difference between attacking Russia on their own territory vs defening Ukraine over Ukraine territory, with their consent.

Edit: So what would happen if Russia flies a fighterjet over NATO territory and they shoot it down. An act of war?
