It is not clear that the pipeline was an act of war, but acts of war can be that simple.

"WW3" is a conceptualization of existential fear, rather than a singular event. The world rallying to one of two sides to make war (or neutrality), is highly unlikely.

I think that denying that ww3 would pose an existential threat to everyone is akin to being a flatearther and an anti waxer. However given todays unfortunate climate it is infinitely more dangerous and war mongorers should be exposed more ferrociously than Russian bots
