I really think youre a very shallow thinker and dont understand strategy or geopolitics. Theyre afraid of confronting the US on something like this because many of them are in on it but at the very least, are all complicit into making their countries pro-American. Its embarrassing for them. Theyd rather go along with 'its russia'. The US bombed the pipeline to undermine Russia and to make it so that europe especially germany doesnt budge to any pressure by Russia and its own population to negotiate and thereby resume gas supply.
Secondly this opens up US with a "tremendous opportunity"

So you have the US not only threatening to putting an end to the pipeline months ago with full knowledge of it with germany but are now bragging about how the destruction of it is now a tremendous opportunity for the US.
