<P> By the timeline of this film, Roth is based in Miami . Though in seemingly poor health, he is extremely wealthy, having made a fortune by running his own organized crime outfit, assisted by his right - hand man, Sicilian Johnny Ola . Roth forms a partnership with Michael Corleone for a profitable business enterprise with the corrupt Cuban government of Fulgencio Batista and a number of major American corporations . Roth secretly plans to assassinate Michael, partly to avenge Moe Greene's murder (as depicted in The Godfather). Roth instructs Ola to befriend Michael's brother Fredo, who inadvertently provides Ola (and Roth) information about Michael that enables them to mount an attack at his Nevada compound . </P> <P> Michael quickly realizes that Roth perpetrated the murder plot . Remembering his father's advice to "keep enemies close," he maintains a good business relationship with Roth . Michael also suspects a mole within the Corleone family aided Roth, and needs time to uncover his identity . </P> <P> During New Year's Eve 1958 / 9, the last night of Batista's rule, Michael orders Roth killed, confiding to Fredo that Roth will not see the New Year . Just as Michael's bodyguard Busetta attempts to smother Roth with a pillow in the hospital, Batista's soldiers storm the facility and kill Busetta . Moments later, Fidel Castro's army enters the city, overthrowing the Batista regime, ruining Roth and Michael's plans . </P> <P> Shortly before the Cuban fiasco, the U.S. Senate begins hearings on organized crime . To eliminate Michael as a competitor, Roth manipulates Corleone family caporegime Frank Pentangeli into testifying against Michael by having the Rosato Brothers, two small - time hoods, attempt to kill Pentangeli . He survives and, believing Michael ordered the attack, agrees to testify against the Corleone Family at a Senate hearing . The hearing is really a set piece arranged by Roth in hopes of removing Michael from the scene; the Senate committee's chief counsel is on Roth's payroll . As a counter-move, Michael has Pentangeli's brother, Vincenzo, flown in from Italy to coerce Petangeli's silence, thus destroying the government's case against Michael . </P>
