The United States, and other advanced nations, will someday be able to produce instruments of death so terrible the world will be in abject terror of itself and its ability to end civilization.... Such war-making weapons should be developed - but only for purposes of discovery and experimentation

Being busy does not always mean real work. The object of all work is production or accomplishment and to either of these ends there must be forethought, system, planning, intelligence, and honest purpose, as well as perspiration. Seeming to do is not doing.
