What? There was no risk and there was a ridiculous amount of money to be made. You have people in the intelligence community talking since the early 2000s how important it is to 'empower poland, to drive a wedge between germany and russia'. The Americans had been threatening to 'do something about' the pipeline for years. And when they did it, the pan European media blackout made sure there was no risk involved. You yourself is a proof of that.
Meanwhile Europe will deindustrialize while paying hand over fist for American gas. They must also continue to dismantle their welfare state and spend that money in American weapons. But european governments don't care, they are all personally invested in american investment funds shares anyway. Why else would the german foreign minister claim that the opinion of german voters are not relevant to her?
Vassals at least had a two way relationship with the King. This is borderline colonial.
