 By the time Kennedy took office, the United Kingdom was ready to decolonize British Guiana and did not fear Jagan's political leanings, yet chose to cooperate in the plot for the sake of good relations with the United States.The CIA cooperated with AFL-CIO, most notably in organizing an 80-day general strike in 1963, backing it up with a strike fund estimated to be over $1 million.The Kennedy Administration put pressure on Harold Macmillan's government to help in its effort, ultimately attaining a promise on July 18, 1963, that Macmillan's government would unseat Jagan.
