"The Defense Department is taking innovative and bold actions to ensure space superiority and secure the nation’s vital interests in space now and in the future."

"it is imperative that the United States possess space capabilities that are so robust as to not only assure our own ability to operate in and through space, but also be able to comprehensively deny it to others.
Space superiority means having better space assets than an opponent. Space supremacy means being able to assert a complete monopoly of such capabilities. The latter is what we must have. If the United States can gain space supremacy, then the capability of any American ally can be multiplied by orders of magnitude, and with the support of the similarly multiplied striking power of our own land- and sea-based air and missile forces be made so formidable as to render any conventional attack unthinkable. On the other hand, should we fail to do so, we will remain so vulnerable as to increasingly invite aggression by ever-more-emboldened revanchist powers.
This battle for space supremacy is one we can win. Neither Russia nor China, nor any other potential adversary, can match us in this area if we put our minds to it."

"U.S. Space Command was created in 1985 by U.S. President Ronald Reagan to manage the “Star Wars” program: a U.S. Cold War plan to use space supremacy to menace the Soviet Union with orbiting battle platforms, powered by nuclear reactors and loaded with space-based weaponry like hypervelocity guns, particle beams and lasers."
