Instead of keeping people who are good at intelligence, Trump fires anybody who insults his. He refuses to read intelligence reports, even when his staff draw pictures of kitties. Trump is so dumb, he thinks the questions on "Are You Smarter Than A Fifth Grader?" are "nasty". If he keeps this up, the entire intelligence community will consist of Moe, Larry, and Shemp, with Curly as the acting DNI.
Before Trump, intelligent people ran intelligence.
