That raises a question: why would Roth agree to let Michael move Klingman out?
I would argue it was just a sacrifice of a pawn in Roth's chess game to get Michael.
Roth was following Bruce Lee's advice:
Don't get set into one form, adapt it and build your own, and let it grow, be like water. Empty your mind, be formless, shapeless — like water. Now you put water in a cup, it becomes the cup; You put water into a bottle it becomes the bottle; You put it in a teapot it becomes the teapot. Now water can flow or it can crash. Be water, my friend.Michael was set on moving into Vegas and it wasn't in Roth's interest (ability???) to confront him directly over Klingman. Far better to scrape and smile and offer no resistance while all the time planning his assassination attempts, while aided by at least one traitor inside the Family.
