Earlier quoted context omitted.
We live in a world where the CIA has a heart attack gun [1], a presidential administration faked evidence of WMD to go to war in Iraq, the CDC conducted secret medical torture on black men with syphilis, and the Pentagon sent JFK proposals to justify a war on Cuba by conducting false flag terrorist attacks against American civilians [2]. (JFK rejected them, apparently.) So I read a list like yours, and read you scoff…
Yes and you know what all those things have in common? Actual evidence which corresponds to real events, and multiple sources confirming that they happened. What Hersh's suppositions have is a stunning lack of verifiable evidence and observably factually incorrect assertions (as in the case of his articles on Nordstream).
The only thing your bullet points were doing is suggesting "look at the delusions of this maniac! He can't be trusted because of them". But because the completely insane shit in my list turned out to be true, Hersh's sorts of claims are at least as plausible as the insane shit I listed in my reply. (And in the case of the first two, they were labeled by bienpensants of all kinds as proof that the claimant was certifiably nuts or at least unworthy of Serious Attention ... until the day they were shown to be true.)
All I'm saying is that, given the factual record of conspiracy and sociopathy on the part of the world's powerful, something like "2013 chemical weapons attack in Syria was a "false flag" staged by the government of Turkey" can't easily be used to dismiss someone as nuts. Not enough evidence? Sure, whatever (but let's wait a decade or two). Crazy though? Nope.
