Imagine what power would accrue to the nation were its military—on the ground, at sea, and in the air—to be backed by a force able to decide whether or how any other country might benefit from objects in orbital space; if that nation were to control access to orbit, securing such objects and benefits for itself. Today, who can do what to whom in or by using orbital space makes a big difference. The world’s significant militaries live by information from and communications through objects in orbital space. Inevitably, sooner or later, one will bid for the comprehensive capacity to control that space. Better that America be first. Establishing the U.S. Space Force will endow people with the mission—the goal, the will, and the interest—to make U.S. control of space happen.
