Yes. I agree, although careerism in the military is maybe not that strong an influence; it is, for sure, but not that strong yet. Careerism in the political class is probably exactly as strong as you claim it is. However, I do hope there are sensible people within that group too, and they heed the underlying message.
The military is still fairly results focused compared to the political class so that at least sort of pushes back on the most flagrant careerism.
