Sure, there are probably some holes/slight inaccuracies in Hersh's story. This particular "debunking" is mostly nitpicking. The tweet about the minesweeper path is a head-scratcher, because it sure looks like the boat slowed down/loitered near both blast sites.

It is interesting that the White House, CIA, State Department, and establishment media class all found the need to promptly respond to what they characterized as a "blog post" and "conspiracy theory" from a "discredited former journalist". Thousands of such speculations are published every day on the internet, and the government does not find the need to respond.

It is also interesting that none of the above government organizations volunteered an alternative explanation for who bombed their ally's critical infrastructure. You would think that the #1 intelligence service in the world would be able to offer some explanation on the matter, almost half a year later, to quell the speculation.
