I don’t understand why you’re going to a website of the USA intelligence apparatus - an apparatus that is currently participating in a genocidal war against Hamas - in order to learn what Hamas calls for. Why not look at what Hamas themselves say?
Why are to adopting the default position that they do call for the destruction of isreal and then asking for sources that prove otherwise? Seems like the people making the claim should be able to provide their source, and if they can’t, they should maybe be asking themselves why they believed it in the first place.
Though, again, it’s not really relevant: genocide is bad.
