Did you actually listen to the interview? What is DT and his followers going to do when they get tough questions?
You also might want to listen to Carly’s interveiw. She actually listened to the question....radical concept!
Walker answered it only because Hewitt gave him all the answers in the question---it was a MUCH different question given to Trump than to Walker (but the same as Carly). NONE of the governors answered it well (surprise). The senators did. That doesn't say much about anything except they get briefings every week on this stuff and absolutely should know it.
And I think Trump did listen, and heard "Kurds." I certainly didn't know Quds or their leader. Most people (even informed ones) won't.
