That's not the primary concern.
The difference between this and historically similar situations is that once you get control of space with these kind of weapons, that's it. Nobody else has a chance to match you unless you allow it, which is of course wide open to arbitrary selectivity and preferential treatment.
If the USA ever has these weapons up there, I think they (meaning the .mil and .gov, not necessarily the civilian population) have demonstrated that they would be quite happy to use them to keep other nations and races down, and they won't give a shit what anyone else thinks because hey - nobody can do anything about it.
I think it's fairly obvious that atinymonkey was referring to the child-in-a-playground-like lack of accountability that the USA .gov displays in international politics, rather than likening them to the dastardly pinkos.
