...reduce risks or not, space exploration assets and hardware
will for the foreseeable future remain inherently vulnerable
to physical high-energy or political-economic calamity.

Certainly your point about spreading space assets around the world,
and using different launch techniques is valid, Raoul.

It only stresses the idea that space enthusiasts shouldn't rigidly rely on or hope in
one nation alone, like the USA, or one organization alone, like NASA, being always able to lead and continue the advance of space exploration and space travel without interruption or retreat or abandonment.
RKA, NASDA, ESA, China's space program, and private space organizations must be built up and matured to a point where they can take the place of the USA and NASA should
overwhelming calamity hit America and its government space program.
