From the Washington Examiner:

A Space Force could help secure critical U.S. satellites and space assets against physical or cyberattack. Given that all bets are off during wartime, having some kind of improved and unified Space Force makes sense. But that new branch must also adhere to a strict and clear mission—such as security in both the physical cyber-realms—or else it will succumb to mission creep. The danger is that another military branch would, like other government programs, start off small but end up continuously expanding its missions in order to justify its existence and fight for a bigger slice of the budget. America needs military branches and units with precise objectives, not another sprawling bureaucracy building useless boondoggles like star destroyers.
