I've already head national "security" experts talk of "hostile Chinese action on the moon" (without specifying further) and "Chinese efforts to control cislunar space" (again without clarifying what that would involve).
Further, citing the need to counter China the US has announced plans to send military satellites to "patrol" the Earth-Moon L2 point (a surveillance satellite as well as an ASAT capable satellite).
In other words, the US is well on its way to bring war to the Moon.
