The most direct evidence of U.S. complicity is a memo from NSC staff member Bob Komer to President John F. Kennedy on the night of the coup, 8 February 1963. The last paragraph reads, "We will make informal friendly noises as soon as we can find out whom to talk with, and ought to recognize as soon as we're sure these guys are firmly in the saddle. CIA had excellent reports on the plotting, but I doubt either they or UK should claim much credit for it."
This financial assistance was valuable, but equally encouraging to the Ba'ath were promises of early recognition and military support. The CIA also provided the list of names of "communists" that the Ba'ath operatives used to gather up potential enemies and torture and kill about 5,000 people in the days immediately following the coup.
