Other historians, however, see these efforts by the CIA as the means to undermine President John F. Kennedy's peace initiative toward Castro. Some revisionist historians claim attempts to eliminate Castro represented a facet of a "Kennedy obsession" purportedly unshared by the rest of Washington. This notion has since been easily dispelled for two reasons: 1) Castro was not the only target of political assassination on Kennedy's agenda and 2) CIA plots to kill Castro existed both before and after Kennedy's presidential tenure.[75]
