I heard them all laughing when he said it. My French is quite bad, so I cannot decide if he intended a joke there. But it fits so very well. In his position, he should not have the time to dig into conspiracy theories. But maybe he was just confronted with this one? Or, on the other hand, he just doesn't care to tell the truth.
It's so perfectly balanced. Everyone has to decide for him/herself in which reality he/she wants to live. I took the one that is the most fun :)
