Someone running for President ought to expect some foreign policy questions. It is OK to say, “I haven’t studied that situation”, or, “No, I don’t care who the head of Pakistan’s internal security is, but if I am President, they will know who I am!”
But Trump wants to be President without doing his homework. And when he flat out doesn’t know what to say, he attacks the person asking.
Not impressed.
He cannot bring himself to simply say, “I don’t know”.
Which is perfectly acceptable btw. I don’t expect our next POTUS to be a know it all. I don’t want that. But I would like to see a little more humility.
