-—RDL, a military base on the moon with WMD that can be delivered to earth is NOT a first strike weapon. It is a final strike weapon.-—
So, in any conceived conflict with china, they will first strike us with their earth based arsenal. And we will retaliate. The threat that they will have missiles left on the moon does not matter at that point. We can retain some of our arsenal on submarines and have the same advantage.
Believe it or not, right now the US has a tremendous first strike advantage over both Russia and China. And they know it. The Russians and the Chinese are working to overcome this advantage, but they haven't been able to for over 60 years and it is doubtful they will be able to, unless they utilize space and the moon. WMD's on the moon would be intended to take away the US first strike capability and preclude the use of nuclear weapons by the US.
