Anyone who has paid the slightest bit of attention to the Middle East for the past 30+ years should know who the Quds force is. They’ve been around since the Iranian revolution, and have been responsible for nearly all of Iran’s overseas activities (read: terrorism) since then. Asking about them is not a “gotcha” question, and confusing them with the Kurds doesn’t really show a level of understanding that a President should have.
Hewitt gave Walker all the info first, and he STILL didn't answer with specifics.
But glad you're up on them.
