And what would be different in their response if it was an attack by NATO or Ukraine?
I need to correct you first on your use of the term "NATO". Russia didn't say NATO, it said the US and Ukraine. Big difference.
And to answer your question very obviously, Russia would run crying to Germany and try to make nice with Germany to collaborate against the US, while at the same time swearing IMMEDIATE repair, and IMMEDIATE re-activation and resumption of gas deliveries to Germany.
Of course none of that happened, because Russia doesn't want to turn it back on, hence why they blew it up, and also isn't going to bother trying to make common cause with Germany, because Russia knows it did the job itself and they'd never be able to fool the Germans into thinking the US did it.
So, the only way Russia can demonstrate they didn't sabotage their own pipelines is by immediately kowtowing to everything NATO wants them to do? Got it.
Why would NATO blow up Russia's pipeline if NATO desperately wants the pipeline to supply gas?
Clearly whoever blew up the pipeline does NOT want it to supply gas, so if it was an enemy of Russia, then Russia should want to thwart said enemy by doing the opposite.
