The more times I watch Made in America, the more I like it.
I think Chase telegraphed it pretty blatantly... Tony got whacked.
Now, what I can't put my finger on, is who ordered it. I'm starting to think it was his own people. They didn't like the way he handled Tony B, which is ultimately what led to the war and got everyone killed. They make remarks on Tony not going to see Syl in the hospital ("Yesterday it was his gout.")
Paulie comes in with a box of scissors toward the end. Butchie was based out of a barber shop. Paulie adored Tony, but he also felt cast aside for Chrissy (he said this to Chrissy explicitly) and he knows Tony suspects him of telling Johnny Sac about the joke; and maybe he suspects that Tony was thinking about whacking him in Florida while they were on the lam. They were on a boat... and then later he has the dream about Pussy where at the end Paulie says "When my time comes, will I stand up?"
In case you can't tell, I just finished my latest rewatch.
