How does president kennedy suggest we ensure that space not be filled with weapons of war?

President John F. Kennedy makes his "moon speech" at Rice "Clearly, it's important, because you've got a president who steps up and says we're going to do it, for the United States over the Soviets in the Cold War space race. "We have vowed that we shall not see space filled with weapons of mass destruction." 

Hope this helps.

That's true, it's a belief in one god
