Roth had just given his blessing! for Michael to move Klingman out and “was gonna turn over his entire Havana gaming empire to Michael”

So why / how would “Michael probably knew, immediately? after the bullets stopped flying in his bedroom” let alone suspect “that Roth was behind the shooting”

I believe, the first, we the audience see Michael could probably know Roth was responsible for the Tahoe shooting was when Michael asked Pentangeli to help Michael take his revenge – cottoning on “why Roth interested himself in a two-bit beef between the Rosato brothers and Pentangeli over three territories in the Bronx”

We the audience know in hindsight that ”Roth had far more to gain by whacking Michael than Pentangeli did”

Pentangeli always! knew never to trust Hyman Roth, Michael to never give his loyalty to Roth before his own blood indeed

If Michael had died?
I never thought Pentangeli had anything to do with the Tahoe shooting!
