Kennedy argues that the difficulty of a goal can itself give the goal value. In the case of the Moon programme, the challenge would require scientific knowledge, engineering skill, organisation and sustained public investment on an exceptional scale. The task was therefore presented not merely as a destination to be reached, but as a test of national capabilities.

In the wider speech, Kennedy links the lunar goal to technological progress and Cold War competition. He acknowledges that the programme will be expensive and difficult, but argues that a demanding objective can concentrate effort and provide a clear measure of achievement. The quotation therefore presents difficulty not as a reason for avoidance, but as a reason for commitment when the challenge is judged important. Its broader idea is that ambitious goals can organise effort, develop capability and reveal what individuals or societies are able to accomplish.

Full quotation

“We choose to go to the Moon. We choose to go to the Moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too.”
