Just to be clear, this isn't "useful [to make] a bomb" - it's useful in a
thermonuclear warhead that already has a primary fission stage using the originally-mentioned highly enriched weapons grade uranium, plus a second fusion stage that (as far as I'm aware) Iran is not working to develop.
edit: phrasing. it feels like we're going around in circles nitpicking based on a poor framing and the tendency for innuendo on this topic
