Huh, I would have said that a question mark is nowhere near enough.
Your stance seems to be that this unsourced conspiracy theory is a story worth discussing because, and only because, it is Seymor Hersh making the claim. Then make that clear in the title: "Seymor Hersh claims America took down Nord Stream", or something. It goes against the standard HN practice of stripping out any such attribution from the title, but it's also not standard practice for an article to only be worthy because of who wrote it.
