lmao is this a joke? This contradicts what you said.
There's "secret evidence" but Blinken denied seeing it.
The evidence is a secret, and even the people who have seen it are a secret! But we should totally just take Israels word for it, everyone except them will lie pathologically.
in any case, I doubt there is any proof that I could offer that would be enough to change your mind. you already know what you want to believe, so this is just online pugilism.
