No, it is simpler. US intelligence agencies pre-911 did not share intelligence or pass along warnings across agency boundaries. That meant events such as the terrorists that went to flight school in Florida, did not get passed along to other agencies. It is why post-911 there is a DNI. However, when you have a chaos president, who distrusts the intelligence agencies, because he doesn't want to hear about Russian interference in his election, it is just as bad.
