If I understand correctly, are you and Pete suggesting that Michael might actually have hired the two gunmen to shoot into his own bedroom, as a pretext by which to go to war with Hyman Roth? I just don't see how that could be credible.

While Michael may not have been the most devoted husband in the world, I can't see him ever doing anything to put Kay directly in the line of fire of a machine gun attack. More broadly, I can't see how Michael would ever have needed to create such a pretext in the first place. He was more than powerful enough to have gone after Roth for any reason he might choose...or for no reason whatsoever. It's not as if he had to answer to anybody, after all.
