He ordered Pentangeli to do nothing, as he did not want a war to interfere with an upcoming deal with Hyman Roth, who supported the Rosato Brothers. Pentangeli took this as an insult and left in anger. Later that night, Michael narrowly escaped an assassination attempt at his home.

Pentangeli agreed, promising to end his feud with the Rosato Brothers and giving the impression that Michael supported their claim,ir so as to give Roth the impression that Michael did not know he was conspiring against him.
