Keep in mind that the assassination attempt was set up to frame Frank Pentangeli. There's no reason to believe that Neri, Rocco, etc. would ever have linked Roth to it. And Roth would have been smart enough to remain safely in the background while the dust settled.
Good point.
I would imagine that Roth's hope was that Pentangeli would be blamed and eliminated. That would give the Rosato Brothers the opening to take over NY operations.
Don't forget that there would also be Willie Cicci or someone else who might have taken over from Pentangeli. We don't know how much influence the Rosatos had and if they would have been in a position to take over at all. But that wouldn't have been Roth's problem anymore..
