I’m not sure I see a big difference between what you wrote and what the article said since you also minimize the likelihood of the attack and the article also talked about their response.
To me it's fair to say it's not a likely scenerio, it's just that they continously say "this would be difficult" at every step. I appreciate the breakdown, but it comes off as trying to convince you it was a near-complete impossibility. I understand it was unlikely, but it was possible, and that makes it severe either way.
Right - I wanted to try to phrase it in a way that replicates the content, but changes the emphasis. Definitely true that they cover all of the same things.
