Who says the SKY is the limit? Who says the SKY is the limit?I'm not for it, either. The point I was trying to make (weakly) is that members of the armed forces can be a bit parochial which is just as myopic as as any O-9 that insists always on fighting the last war.
It's very human to think, if we die, the world will crumble in no time. We can say with some justification that the world since 1941 owes the the United States Military (meaning men, women, children, fathers, mothers, brothers, sisters, etal), all branches, more that it can ever repay.
Now, at one time or another, every branch has played a part in making it a better world, and the job continues. Who knows what mix will be most needed for the next crisis, even while the present one goes on. Who knows whether the next hero will make all the papers or labor anonomously.
Each branch is tasked to keep accomplishing its mission with ever greater efficiency. All military people should stop worrying about trying to abolish the other guys' jobs and think about better ways to do the one assigned.
