Point (b) isn't related to relative dominance in space, it's achievable with only a minimum absolute degree of capability. They could still deploy space weapons, even if their capabilities are far inferior. Point (a) just begs the question. What is the value of "US domination of the space"? What does it cost us if the Chinese strength increases in some way? I submit that in the same way we say that the space program helps the USA broadly, it's also true that in the long run, success in space by anyone in the world helps everyone in the world.
