“It was a single short sentence, why is that your analysis?”
Because Russia is taking out power plants in Ukraine, and Russia has been interfering in US elections since Trump decided to run - hence it must be a Russian operation. In fact, I wouldn’t be surprised if 51 former intelligence agents claim the same.
If you don’t accept that rationale, then you must be a Putin supporter.
That was a goofy post, it explained nothing about why you think these attacks “have all the earmarks of a Russian operation”.
