In my mind, the Ukrainians are the only party who could blow the pipelines without being dirty. It's a strategic asset of a country they're in an active war with.
Imagine if they did take credit for this, Russia could respond with nukes or chemical weapons. It could also bite them that deep in the cold of winter, when everyone is wearing coats in doors for months, that the Germans start to resent sending military equipment to Ukraine.
This act will put pressure on Ukraine. Also not super great for the environment. as well. Another often overlooked victim.
What makes it their gas?
People voted and lived in a society where things were handled. You voted and kept your government because things were handled. You voted the way you did because you were satisfied you could keep yourself warm in the winter at a fair price. Eventually, you consider that right yours, since it was described as something you have access to.
Then suddenly someone you voted for decides, "hey, I know my party ran on getting that pipeline approved, and we invested in green energy as a certain ratio based on getting this gas to you when you need it, but guess what.... We've changed our mind. There are outside things more important than your ability to heat your home for a price you can afford."
I'd consider that the politician turning off my access to affordable life sustaining gas.
Just pointing out that it isn’t like you’re talking about your country’s national reserves that are being sold elsewhere instead of to you.
I don’t mean to sound disparaging but a good set of winter clothes will ensure survival through the winter better than whatever gas/price ratio you feel entitled to.
