We hear something in Greg's statement there of Iran's rhetoric when they use the word terrorism. The U.S. uses the word terrorism about Iran. Iran is happy to turn that back and say, you say we're the terrorists. We say you're the terrorists. And here's a reality that the U.S. has to consider as it watches for possible Iranian retaliation.

Concerning the use of ‘when’ in the first bolded part, what does ‘when’ mean in that sentence?
Does it modify the verb ‘hear’, meaning the time when we hear that?

No. If that were so, the "when"-clause could be fronted, but it can't:

When they use the word 'terrorism,' we hear something in Greg's statement there.

Rather, the "when"-clause modifies the noun phrase "Iran's rhetoric," which is the object of "of." The "of"-phrase is extraposed. It modifies "something."

We hear [something [of Iran's rhetoric [when they use the word terrorism]]] in Greg's statement there.

I made up a sentence. Is it right?

Does it have a similar function where ‘when -clause’ modifies a noun, as in the original post?

Yes, but I find that sentence rather awkward with know. I'd prefer something like this: I heard about your response when you got that gift last night.
