What I never understood. Sollozzo is backed by Tattaglia, and represents them in the Corleone drug meeting. But is he more of a Tattaglia business partner, or a regular soldier? What I mean is, are his actions his own, or ordered by Phillip Tattaglia. The assassination, Tom's kidnapping, the others I can't think of, but my question applies to them to.

And how do you suppose they flipped Paulie? Seems to me all they had to do was point out the obvious. Vito was getting old, Paulie was on his way up, and they could use him to fill the power vacuum/give him a part in the heroin trade.
