When I enlisted in the US Army they made us memorize our chain of command all the way up to the Commander in Chief (POTAS). I still remember who was in charge back then, but I didn't know who the current Secretary of Defense was until you told me just now. It's weird, because that used to be something most of us citizens knew, but over the last 6 years everything has gone so fucky that we can't seem to keep track of everything any more. I blame it on the very intentional firehose of falsehood that is aimed directly at each of us every single day now.
