Would be good to not depend on the US that much any longer, since they have proven to be such an unreliable "partner". Even in a non-Trump future one cannot rely upon some future election not resulting in some similar disaster. Better to pull out, before some hothead gets weird ideas about that gold.
Maybe the fact that US soldiers and military bases exist inside Germany's borders is slightly more important than where the gold is. First regain your sovereignty, I'd say.
I am guessing that these bases are one of the last things to go. Would be a major diplomatic incident. But then again Trump creates those for breakfast, so who knows when we finally have had enough.
I’m pretty sure Trump thought or heard mention of Minchin (first Trump Treasury Secretary) visit to Fort Knox in 2017 recent to that comment and just blurted out the first thing that came to his mind - like most of his off the cuff remarks, it doesn’t make any sense on close examination but appeals to MAGA supporters.
Like most off the cuff Trump remarks - it made headlines for a while but nothing came of it, it’s not in Project 2025 and Musk fell out of favor with Trump for whatever reason. The combo of Musk and Trump was just dry kindling for the forest fire of baseless conspiracy theories with no founding in reality - like “omg, government incompetence lost the gold, Biden stole the gold after Trump didn’t lose in 2020” since Minchin told Trump what he saw in 2017 and Minchin posted interior photos of Knox with his wife at the time on social media. Since it disappeared from news after the remark and there is no one in current Trump admin who would pass up an opportunity for internet karma, a reasonable person can conclude it was just another bit of flooding the zone with information - credit where credit is due - several strategies executed by Trump that were outlined in Jacques Ellul seminal book - Propaganda.
