Nope, show-offability is the deterrence (as snafu352 pointed the right term) made visible. It does not imply real employment (yet).
As said above:
Quoting a General from the Forces Aériennes Stratégiques:
"Un convoi nucléaire bien en vue lorsque tel satellite de tel pays passe au dessus d'Istres, ça fait toujours son petit effet."
"A prominent nuclear convoy when a satellite of
that country passes over Istres, that always impress your guests!"

Re: National pride?
Why not. But that's (by far) not the main reason. Only a bonus.
The air component:
1/ provides a more flexible deterrent
2/ maintains high level of skills in the industry
3/ maintains high level of skills in the forces
4/ participates in political weight in international relationships
5/ adds a bit to national pride.

Mildave: Agreed on flexibility.
