Basocally everyone wanted NS2 to be gone, including the Russians. So in all honesty, I'd expect saboteurs frok NATO country A helping out saboteurs from non-NATO country B with explosives and detonators if needed.

By the way, nobody wanted NS2 by the time it was technologocally ready. Funny enough, if Trump wouldn't have been president a deal for CNG anf LNG would have been had a lot easier and earlier.
