The Sound and the Fury is a Faulkner novel? It’s been too long though and IDK if it quotes Macbeth past the title.

Even if true it’s not relevant. He’s a Nazi in the US, if something goes south for him here he can’t flee to the US.

This is my theory, less that he wants access to memorabilia and more he heard that Nazis fled there and survived and he’s hedging his backup plan

While true we’re also in the ‘do literally anything you can to stop or stall the fascists"’ stage and this denies a greater Republican controlled house
