Kennedy adopted Keynesian economics and proposed a tax cut bill that was passed into law as the Revenue Act of 1964. Kennedy also established the Peace Corps and promised to land an American on the moon, thereby intensifying the Space Race with the Soviet Union. Kennedy faced a dilemma: if the U.S. attacked the sites, it might lead to nuclear war with the U.S.S.R., but if the U.S. did nothing, it would appear weak. Finally, he announced that the U.S. would begin a naval blockade of Cuba in order to intercept arms shipments.On October 23, in a unanimous vote, the OAS approved a resolution that endorsed the blockade and called for the removal of the Soviet nuclear weapons from Cuba. That same day, Stevenson presented the U.S. case to the UN Security Council, though the Soviet Union's veto power precluded the possibility of passing a Security Council resolution.
