No no no, you got it all wrong. Using drones/planes to kill military (and pretty often civilian) targets on another country’s territory is an act of war only if you are not the US.

I see why his take on this is the antipod of yours, but you clearly won’t achieve anything by so easily shifting to aggression and leaving the discussion on a tantrum.
