Basically a TL;DR
Russians not only know that the USA sabotaged the two natural gas pipelines to Germany, but they know which US Navy ship was responsible: USS Kearsarge.
It was 30 km from Nord Stream-1 gas pipeline and 50 km from Nord Stream-2 gas pipeline.
Plus they know USA threatened the pipeline:
Victoria Nuland Flashback: “If Russia invades Ukraine, one way or another, Nord Stream 2 will not move forward.”
Also, The American's CIA warned of Nord Stream attack.
Finally; Not an accident!
