It's not that there's nothing in Fort Knox, there is: it's a massive store of gold-plated tungsten.
Until the elite allow the people to audit their own gold, prove it's not tungsten.
It's the sort of scam the banksters and fascist, neo-Nazi warmongering elite of the US would be proud of: IMO they've flogged off the US people's treasure on the sly to a pack of bankster mates, and they'd be lynched if the people found out.
