Indeed, it seems to be doubling, tripling, and even quadrupling its lethality every few years. And the result is that we are outdistancing not merely the capabilities of our enemies but our allies as well - many of whom who have not fought in decades - at such a dizzying pace that our sheer destructive power makes it hard to work with others in joint operations.
