How long before Indiana Jones is told by Wokeys that he has to to return all the items he stole/gave to a museum from other countries?

The Museum curator explicitly refers to an international treaty for antiquities in the first movie. I think they have a condescending-yet-possibly-accurate-for-the-time notion that they have the resources to study, preserve, and make available the pieces which Dr. Jones the Younger "acquires" in his..."travels"...

Just think, if Europeans hadn’t stolen all that stuff from the Middle East, Islamic state would have dynamited it anyway…😂
