Not really? you are simply using a grammatical argument while completely ignoring the substance which is simply a dishonest practice, the meaning is easily inferred by the context yet you zeroed on it while completely avoiding the topic in question.
The term "denuclearization" is used in informal and formal settings to refer to the term "nuclear disarmament".
For example

Going full "ackchyually" on the term is ridiculous, its good for academia and its good for the press, by denuclearization we are talking about Iran abandoning its nuclear weapons program.
Nope, the JCPOA was made to stop Iran from getting nuclear weapons and it worked, was negotiated by the collective West and endorsed by the entirety of the US nuclear weapon community.
We never even started in the first place, you claimed Israel is looking to exhaust diplomatic options before war, yet Netanyahu has been pushing for war since at least 2012.
