Can you imagine if this is true, and Germany gets robbed trying to transport that much gold back to Germany. It would be the biggest heist in history.
According to Google AI, the biggest heist in history was in 2003, when the Iraq Central Bank was robbed for 1 billion dollars by Saddam Hussein, but I don't count him because he had too many advantages.
Also in 2003, thieves stole over $100 million in diamonds, gold, and jewelry from a vault in Belgium, often called the "heist of the century." It is called the Antwerp Diamond Heist.
