according to those who have heard all the interviews some of the candidates were told who the players were and then asked to discuss and some were gotcha quizzed on who the players were before the discussions.. it’s an old interview ploy to discredit those you want to discredit..
Trump got the former treatment - Hewitt mentioned Quds and General Sulemani, asked Trump if he knew who they were, Trump said yes, and then Hewitt continued on with his question. Trump, unprompted, then interjected with a comment about how the Kurds have been treated (revealing Trump's apparent confusion between the Quds Forces and the Kurds, and his apparent ignorance of General Sulemani). He wasn't being quizzed, there was no "gotcha" question. He showed his ignorance on his own, without prompting.
