ver.[48] It is gathering strength in many other fields.

Disarmament is a long way from being a reality. But all nations of the
world are striving for it, or at least giving lipservice to its
principles, so it may one day emerge as a reality. If this happens,
space exploration again may be a most important element in taking up the
slack which a prominent reduction in defense activity could not help but
bring about.

Indeed, there are some who already foresee a complete substitution of
space for defense, and who prognosticate that in the 1990's "the economy
of nations is now based on the astronautics industry, instead of
war."[49] Certainly, some new economic force would be crucial to nations
deprived of the need for devising and manufacturing weapons.
