A bit of research...

On Wednesday, US District Court Judge Royce C. Lamberth ordered Russia to pay fines of $50,000 per day until it returns the Schneersohn Collection of books and manuscripts to Chabad in Brooklyn.

Lamberth is known as a flamboyant judge who issues unenforceable rulings against foreign governments. This ruling is no exception.
The books and manuscripts last belonged to a Schneersohn in 1940, when they were seized by the Nazis after Rabbi Yosef Yitzchok Schneersohn, the Lubavitcher Rebbe of that era, was rescued from them by German Military Intelligence and the US Government, which had not yet entered the war against Germany.
Infamously, just after the Germans handed over the great Chabad leader to the US just across the border in then-neutral Latvia, Schneersohn asked the Americans to go into Poland and save his silver, his household goods, and his books.

No one should think that Russia is a good actor here – it isn't.
The problem is, Chabad really isn't either.  FailedMessiah
