> This is not an act of war with Germany.
It can be construed as such, but certainly not by Germany. They are not strong enough to make a stink about it. Powerful states can take offense at the smallest thing. Weaker nations put up with lots of shit. (Is not, for example, what is done to Russia economic warfare? Do you see them declaring war? No. Because they are weaker.)
So boundary of what constitute an act of war is somewhat fuzzy not completely crisp.
> This happened in international waters.
Yes, and NATO waters.
> The pipeline is already shut down. This does not affect Germany's gas supply, as they were already receiving no gas from Nordstream
Addressed multiple times in this thread. Options closed. Decision trees altered. Game theory.
p.s.
A nice map to go with this thread. The remaining functional gas pipelines from Russia to Germany both go through Poland and Ukraine. Both Poland and Ukraine have 'difficult' relations with Germany and 'hostile' relations with Russia.
