The ones that care are relistic: Ukraine support against Russia right now makes sense geopolitical. Doesn’t mean they won’t remember that an ally was willing to conduct an active act of war against their infrastructure for their own stupid narratives - as if it wasn’t actually unused already anyway. The fact that it was basically already discarded only means it’s not of immidiate importance, but I’m quite sure Ukraine is aiming for more cooperation with Germany and the EU. And you can bet that there are poeple who will take that into account when evaluating how much Ukraine can be trusted.

It’s like slashing the tires on a car you sold for scrap last week.

More like you plan to sell it for scrap anyway and then your neighbour smashes the wind shields on purpose. It’s not an actual loss concerning you, but the act itself will be remembered.
