What does the underlined part mean?
"If this situation itself does not speak of a political deadlock , then it is hard to know what does ."
Is the underlined part an idiom ? Can I repeat it in another similar structure and , for example, say: "If she does not dance, then it is hard to know what does."?
Is it an fixed idiom?
Is "what" (in my example) a pronoun?
