In Kennedy's January 1961 State of the Union address, he had suggested international cooperation in space. Khrushchev declined, as the Soviets did not wish to reveal the status of their rocketry and space capabilities. Early in his presidency, Kennedy was poised to dismantle the manned space program but postponed any decision out of deference to Johnson, who had been a strong supporter of the space program in the Senate. Kennedy's advisors speculated that a Moon flight would be prohibitively expensive, and he was considering plans to dismantle the Apollo program due to its cost.
